Answer:
A
Step-by-step explanation:
Using the sine ratio on the right triangle on the right to find x
sin30° = =
( multiply both sides by 70 )
70 × sin30° = x , thus
x = 35
-----------------------------------------------
Using the sine ratio on the right triangle on the left to find y
sin42° = =
=
( multiply both sides by y )
y × sin42° = 35 ( divide both sides by sin42° )
y = ≈ 52.3 ( to the nearest tenth ) → A
