Question 1:
AB = 9 ... Because opposite sides are equal
AC = 22 .... Just multiply 11 by 2
BE = 7 ... Same as the other half the diagonal
m∠BAD = 49 degrees... Same as ∠ACD
m∠ADC = 77 degrees... Add 27 and 49
m∠ABD = 60 degrees ... 180 - 27 - 49 - 43
Question 2:
7x -13 + 4x - 5 = 180
11x = 198
x = 18
7x - 13 = 7(18) - 13 =113
m∠PSR = 113
Question 3:
16x - 17 = 10x + 1
6x = 18
x=3
m∠QPT = 90 - (10x+1) = 59
Have an awesome day! :)
