Question

Pls help me !!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

9.89 m

Step-by-step explanation:

AC is the hypotenuse (H)

x is the opposite (O)

O and H are in sine

sin=O/H

H=O/sin

H=7.9/sin(53)

=9.89187169943418

Answer 2

Answer:

AC= 13.144

Step-by-step explanation:

cos ∅ =  Adjacent/ Hypotenuse

cos (53°) = x/AC

cos (53°) = 7.9/AC

(0.601).(AC)=7.9

AC=(7.9)/(0.601)

AC=  13.144 (3 S.F)
