Answer:

$s \div 2\pi \: h = r$

Step-by-step explanation:

lisabon 2012 [21]

Answer:

180 - 46 - 83 = 51 is the measure of angle C

the exterior angle at angle C, and angle C, are supplementary. since angle C is 51 because of the interior angle triangle sum theorem, then the exterior angle is: 180 -51 = 129 degrees.

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°
