Answer:

Step-by-step 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.
