Gym members are instructed to lift their legs at a 30° angle during leg lifts. One member has legs that are 33 inches long. What is the height (in inches) of the member’s feet during the leg lift? If necessary, round decimal answers to the nearest tenth.

answer: x=3 and y=4

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

a is the best answer choice
