Example Question #1 :How To Find The Length Of The Side Of A Right Triangle

A right triangle has one side equal to 5 and its hypotenuse equal to 14. Its third side is equal to:

Possible Answers:

171

13.07

14.87

Correct answer:

13.07

Explanation:

The Pythagorean Theorem gives usa²+b²=c²for a right triangle, wherecis the hypotenuse andaandbare the smaller sides. Hereais equal to 5 andcis equal to 14, sob²= 14²– 5²= 171. Thereforebis equal to the square root of 171 or approximately 13.07.

Example Question #9 :How To Find The Length Of The Side Of A Right Triangle

Which of the following could NOT be the lengths of the sides of a right triangle?

Possible Answers:

12, 16, 20

5, 7, 10

5, 12, 13

8, 15, 17

14, 48, 50

Correct answer:

5, 7, 10

Explanation:

We use the Pythagorean Theorem and we calculate that 25 + 49 is not equal to 100.
All of the other answer choices observe the theorema²+b²=c²

Example Question #2 :How To Find The Length Of The Side Of A Right Triangle

Which set of sides could make a right triangle?

Possible Answers:

4, 6, 9

6, 7, 8

10, 12, 16

9, 12, 15

Correct answer:

9, 12, 15

Explanation:

By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

Example Question #1 :How To Find The Length Of The Side Of A Right Triangle

A right triangle with a base of 12 and hypotenuse of 15 is shown below. Find x.

Possible Answers:

5.5

4.5

3.5

Correct answer:

Explanation:

Using the Pythagorean Theorem, the height of the right triangle is found to be = √(〖15〗²–〖12〗²) = 9, so x=9 – 5=4

Example Question #2 :How To Find The Length Of The Side Of A Right Triangle

A right triangle has sides of 36 and 39(hypotenuse). Find the length of the third side

Possible Answers:

33√2

12 √6

Correct answer:

Explanation:

use the pythagorean theorem:

a²+ b²= c²; a and b are sides, c is the hypotenuse

a²+ 1296 = 1521

a²= 225

a = 15

Example Question #3 :How To Find The Length Of The Side Of A Right Triangle

Bob the Helicopter is at 30,000 ft. above sea level, and as viewed on a map his airport is 40,000 ft. away. If Bob travels in a straight line to his airport at 250 feet per second, how many minutes will it take him to arrive?

Possible Answers:

1 hour and 45 minutes

2 hours and 30 minutes

3 minutes and 50 seconds

3 minutes and 20 seconds

4 hours and 0 minutes

Correct answer:

3 minutes and 20 seconds

Explanation:

Draw a right triangle with a height of 30,000 ft. and a base of 40,000 ft. The hypotenuse, or distance travelled, is then 50,000ft using the Pythagorean Theorem. Then dividing distance by speed will give us time, which is 200 seconds, or 3 minutes and 20 seconds.

Example Question #4 :How To Find The Length Of The Side Of A Right Triangle

A right triangle has two sides, 9 andx, and a hypotenuse of 15. What isx?

Possible Answers:

Correct answer:

Explanation:

We can use the Pythagorean Theorem to solve forx.

9²+x²= 15²

81 +x²= 225

x²= 144

x= 12

Example Question #5 :How To Find The Length Of The Side Of A Right Triangle

The area of a right traingle is 42. One of the legs has a length of 12. What is the length of the other leg?

Possible Answers:

$11$

$9$

$6$

$5$

$7$

Correct answer:

$7$

Explanation:

$Area= \frac{1}{2}\times base\times height$

$42=\frac{1}{2}\times base\times 12$

$42=6\times base$

$base=7$

Example Question #141 :Plane Geometry

Triangle

$\left ( \bigtriangleup ABC \textup{ is a right triangle where } \angle B \textup{ is a right angle}\right)$

If $\angle A=30^{\circ}$ and $\overline{AB}=4$ , what is the length of $\overline{BC}$ ?

Possible Answers:

$\frac{4\sqrt{3}}{3}$

$\frac{4}{3}$

Correct answer:

$\frac{4\sqrt{3}}{3}$

Explanation:

AB is the leg adjacent to Angle A and BC is the leg opposite Angle A.

Since we have a $30^{\circ}-60^{\circ}-90^{\circ}$ triangle, the opposites sides of those angles will be in the ratio $x-x\sqrt{3}-2x$ .

Here, we know the side opposite the sixty degree angle. Thus, we can set that value equal to $x\sqrt{3}$ .

$4=x\sqrt{3}$

$\frac{4}{\sqrt{3}}=\frac{x\sqrt{3}}{\sqrt{3}}$

$\frac{4}{\sqrt{3}}\cdot \frac{\sqrt{3}}{\sqrt{3}}=x$

$x=\frac{4\sqrt{3}}{3}$

which also means

$\overline{BC}=\frac{4\sqrt{3}}{3}$

Report an Error

Example Question #6 :How To Find The Length Of The Side Of A Right Triangle

Solve forx.

Possible Answers:

Correct answer:

Explanation:

Use the Pythagorean Theorem. Leta= 8 andc= 10 (because it is the hypotenuse)

$\small a^2+x^2=c^2$

$\small 8^2+x^2=10^2$

$\small 64+x^2=100$

$\small x^2=100-64=36$

$\small x=6$
