Idon't know how to get to x. this is what i have so far.

Using Pythagorean theorem
9.5^2 + 18.9^2 =  90.25 + 357.21 = 447.46

√447.46 = 21.15

x = 21.15

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
