Question

Giving a lot of points help!

What is the value of x?

Answer 1

Explanation:

a triangle = 180

Q = 180 - (90 + 45)

Q = 180 - 135

Q = 45

Answer 2

Explanation:

With reference angle 60°

perpendicular (p) = 2√3

hypotenuse (h) = ?

We know

sin 60° = p/h

√3/2 = 2√3 / h

cross multiply

h =( 2√3 * 2)/ √3

therefore h = 4

So

Now

with reference angle 45°

perpendicular (p) = x

base (b) = 4

Now

tan 45° = p/b

1 = x / 4

Therefore x = 4
