Answer:
Idk about the first one, my answer is 86.6 but here one of the option is 8.6 and second one, answer is 8.
Step-by-step explanation:
first one : you have to draw a triangle. the base is going to be 50 m and we have to find the height, we only have adjacent of triangle so we can use the tangent formula
tan 60 = x / 50
x = 50 tan 60
x = 86.6 m
Second one:
sin = opp / hyp
sin 45 = 4√2 / x
x = 4√2 / sin 45
x = 8
