Question

Tolongg yhh di jwab pliss...

Answer 1

P1 = 128 drajat
p2 = 180 - 128 = 52 : 2 = 26 drajat
p3 = 26 drajat

r1 = p2 + p3 = 52 drajat
r2 = 52 drajat
r3 = 180 - (r1+r2) = 180 - 104 = 76 drajat

**maaf kalau salah

Answer 2

P₂ = (180 - 128)/2
P₂ = 52/2
P₂ = 26°

P₃ = P₂
P₃ = 26°

R₁ = 180° - P₁ (sepihak)
R₁ = 180° - 128°
R₁ = 52°

R₂ = R₁
R₂ = 52°

R₃ = 180° - (R₁ + R₂)
R₃ = 180° - (52° + 52°)
R₃ = 180° - 104°
R₃ = 76°
