Question

In meters, find the value of x?

Answer 1

x= 75m

Explanation:

If we call the angle in the bottom left θ, then the sinθ=(opposite side)/(hypotenuse).

For the smaller triangle:

sinθ=30/50

And for the bigger triangle:

sinθ=45/x

So:

30/50=sinθ=45/x

30/50=45/x

x=(45•50)/30=2250/30=75

So x= 75 meters

Answer 2

75 meters

Explanation:

30/50 = 45/x

x = 75
