1. in a right triangle, the length of the hypotenuse is 20 inches and the length of one leg is 15 inches. what
is the length of the other leg in inches?
a. 5
b. 5√ 7
c. 25
d. √ 7

Answer

B. 5√ 7

Explanation

When solving the lengths of a right triangle we use either the trigonometric ratio or the pythagoras theorem.

c² = a² + b²

Where a and b are the legs of the triangle and c is the hypotenuse.

20² = 15² + b²

b² = 20² - 15²

   = 400 - 225

    = 175

b = √175

  = √(25 × 7)

   = 5√7 inches

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )
