Answer:
angle 1 = 72 angle 2= 36 angle 3 = 18 angle 4=144
Step-by-step explanation:
take 90 and subtract 18
thats 72
72 is direct opposite of angle 1
so angle 1 =72
so the top triangle is 18+18=36
180-36=144
adjcent angle 4 is congruent so 4 =144
angle 2+4=180
angle 2 =36
angle 3=18 due to top triangle is congruent
