Answer:
x = 3
Step-by-step explanation:
Given
15x - 3(3x + 4) = 6 ← distribute and simplify left side
15x - 9x - 12 = 6
6x - 12 = 6 ( add 12 to both sides )
6x = 18 ( divide both sides by 6 )
x = 3
2x-3/4=1/2
The answer is X=5/8
Set the angles equal because they are vertical angles
150=5m
30=m (divide both sides by 5)
Answer:
∠ R ≈ 39°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos R =
=
=
, then
∠ R =
(
) ≈ 39° ( to the nearest degree )
