Answer:
B
Step-by-step explanation:
You have given angle x and the hypotenuse you are asked to find the adjacent side of the triangle so you would be using
Cosθ = Adjacent/hypotenuse.
cos49 = adjacent/4
1.32 = adjacent/4
2.62 = adjacent
VX = 2.6
Remember!
SOH
Sinθ = opposite/hypotenuse
CAH
Cosθ = adjacent/hypotenuse
TOA
Tanθ = opposite/adjacent
