Answer:
Pretty sure it's 20.24.
Step-by-step explanation:
Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.
tan(39) =
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 =
Now, switch the sides to make it easier.
= 0.8097
Multiply both sides by 25.
x = 20.24
Answer:
x = 27
Step-by-step explanation:
This angle is a right angle, meaning 90 degrees, as whenever it's a right angle, there's a small square on the angle which u can see at the bottom left, so:
x + 8 + 2x = 90
3x + 8 = 90
subtract 8 from both sides
3x = 82
divide by 3
x = 27 1/3
