Answer:
∠ U = 22.62°
Step-by-step explanation:
We can use the trigonometric expression to find ∠U by using the ratio:
sin(θ) = opposite/ hypotenuse
=> sin ∠U = 7.5/ 19.5
=> ∠ U =
( 7.5/ 19.5)
∴ ∠ U = 22.619° ≈ 22.62°
Answer:
x = 25
Step-by-step explanation:
it's an isosceles triangle so base angles are the same
3x - 30 = 45
Add 30 on both sides
3x = 75
divide both sides by 3
x = 25
