Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2

Which expression can be used to find m pls help
natali 33 [55]

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 = sin^{-1}( 7.5/ 19.5)

∴ ∠ U = 22.619° ≈ 22.62°
