Question

pls help with this triangle question​

Answer 1

$\mathcal {\orange {SOL:-}}$

vertex angle = 80°

let the base angle be x.

x° = x° = 2x° both base agles

now,

2x + 80 = 180 ..... sum of all angles of triangle

2x = 180 -80

2x = 100

x = 50°

measure of base angle is 50°

Answer 2

Answer:

50°

Step-by-step explanation:

let the bases = x

vertex angle = 80°

According to question

X+X+80°= 180°

2x = 180°- 80°

2x = 100°

X = 100/2

X = 50°
