Answer:
Explanation:
Because of the givens (a right angle a common Hypotenuse and a leg in each triangle) ΔSUT and ΔSUV are congruent. HL
That means that < SUT = < SUV so what you get out of that is
w + 10 = 3w Subtract w from both sides.
w - w + 10 = 3w - w
10 = 2w Divide both sides by 2
10/2 = 2w/2
w = 5
I don't know what A with a check mark below it is.
