Answer 1

Answer:

please refer the attachment for procedure

Step-by-step explanation:

• angle A = 20°
• angle B = 80°
• angle C = 80°

Answer 2

$x + 4x + 4x = 180 \\ 9x = 180 \\ x = \frac{180}{9 } \\ \\ x = 20 \\ three \: angles \: of \: triangle \: are \: 20 \\ 80 \\ 80$

angle

• a = 20
• b = 80
• c = 80
