Question

In the triangle below, which equation can be used to solve for x?

a)x=13sin50/sin75
b)x=13sin75/sin50
c)13sin55/sin75
d)13sin75/sin55

Answer 1

D. on edge

Explanation:

Answer 2

d)13sin75/sin55

Explanation:

1)Given

inΔVWU, ∠V= 75°

∠U= 50°

Finding ∠W:

∠W= 180-(75+50)

=180-(125)

= 55

Now finding x, using law of sine

x/sinV = 13/sinW

Putting the values in above we get:

x/sin75=13/sin55

Re-arranging, we get:

x= 13sin75/sin55 !
