Jennifer needs to use a ladder to clean a second floor window on a building. If the window is 13ft above the ground and the base of the ladder is 4ft from the building, which equation below can be used to determine the length of the Ladder needed to reach the window

A 42 + 139 = 2

В

4² + x² = 13²

С

132_4? = ?

D

132P = 42

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
