## Right-Triangle Word Problems

What is a right-triangle word problem.

## MathHelp.com

For the base, I'll use the cosine ratio:

ladder top height: about 5.20 m

As usual, I'll start with a picture, using "alpha" to stand for the base angle:

m(α) = sin −1 (4/5) = 53.13010235...

(Remember that m(α) means "the measure of the angle α".)

92919800×tan(17/60°) = b = 459501.4065...

1.3 × 110 = 143 1.5 × 110 = 165

Now that I have the lengths of the two legs, I can set up a triangle:

I can find the distance between the starting and ending points by using the Pythagorean Theorem :

143 2 + 165 2 = c 2 20449 + 27225 = c 2 47674 = c 2 c = 218.3437657...

tan −1 (165/143) = θ = 49.08561678...

## Triangle Solving Practice

Try to solve each triangle yourself first, using pen and paper.

Then use the buttons to solve it step-by-step (more Instructions below).

## Instructions

- Look at the triangle and decide whether you need to find another angle using 180°, or use the sine rule, or use the cosine rule. Click your choice.
- The formula you chose appears, now click on the variable you want to find.
- The calculation is done for you.
- Click again for other rules until you have solved the triangle.

Note: answers are rounded to 1 decimal place.

## What Does "AAS", "ASA" etc Mean?

It means which sides or angles we already know:

- Behavior . Certain behavior(s) is (are) common to the incidents. For example, making excessive noise, robbing people or businesses, driving under the influence, crashing vehicles, dealing drugs, stealing cars. There are many different behaviors that might constitute problems.
- Place . Certain places can be common to incidents. Incidents involving one or more problem behaviors may occur at, for example, a street corner, a house, a business, a park, a neighborhood, or a school. Some incidents occur in abstract places such as cyberspace, on the telephone, or through other information networks.
- Persons . Certain individuals or groups of people can be common to incidents. These people could be either offenders or victims. Incidents involving one or more behaviors, occurring in one or more places may be attributed to, for example, a youth gang, a lone person, a group of prostitutes, a group of chronic inebriates, or a property owner. Or incidents may be causing harm to, for example, residents of a neighborhood, senior citizens, young children, or a lone individual.
- Time . Certain times can be common to incidents. Incidents involving one or more behaviors, in one or more places, caused by or affecting one or more people may happen at, for example, traffic rush hour, bar closing time, the holiday shopping season, or during an annual festival.

- Repeat offenders attacking different targets at different places.
- Repeat victims repeatedly attacked by different offenders at different places.
- Repeat places (or hot spots) involving different offenders and different targets interacting at the same place.

- a suitable target is available.
- there is the lack of a suitable guardian to prevent the crime from happening.
- a motivated offender is present.

He turned and dug through the dirt diagonally for 80 80 meters until he was above ground.

Six Different Types If you need to solve a triangle right now choose one of the six options below: Which Sides or Angles do you know already? (Click on the image or link) AAA Three Angles AAS Two Angles and a Side not between Two Angles and a Side between Two Sides and an Angle between Two Sides and an Angle not between Three Sides

We can now use the right triangle BDC to determine h as follows: h AC = sin(43.2 ∘) h = AC ⋅ sin(43.2 ∘) ≈ 59.980 So the top of the flagpole is 59.980 feet above the ground. This is the same answer we obtained in Exercise 3.4.1. Exercise 3.4.1 A bridge is to be built across a river.

Once you've learned about trigonometric ratios (and their inverses), you can solve triangles. Naturally, many of these triangles will be presented in the context of word problems. A good first step, after reading the entire exercise, is to draw a right triangle and try to figure out how to label it.

Step 1: Identify the givens. Step 2: Label the corresponding sides of the congruent triangles. Step 3: Use the data and side lengths of the triangles to solve the word problem. Equations &...

The problem analysis triangle (sometimes referred to as the crime triangle) provides a way of thinking about recurring problems of crime and disorder. This idea assumes that crime or disorder results when (1) likely offenders and (2) suitable targets come together in (3) time and space, in the absence of capable guardians for that target.

The Triangle Inequality says that in a nondegenerate triangle: . That is, the sum of the lengths of any two sides is larger than the length of the third side. In degenerate triangles, the strict inequality must be replaced by "greater than or equal to.". The Triangle Inequality can also be extended to other polygons.The lengths can only be the sides of a nondegenerate -gon if for .

7 years ago. Imagine all of the lines that form the exterior angles extending outward to infinity. Now, imagine zooming out from the pentagon, until it shrinks to a point. You'll see all of the lines that we extended just converging to that point. Now, it's clear that all of those angles form a full circle, which is 360°.
