Question

In an isosceles triangle, the base angles are equal. The vertex angle is 80degrees. So each base angle = _______ degrees. *​

Answer 1

Step-by-step explanation:

80°+x+x=108°

2x=180°-80°

2x=100°

x=50°

Answer 2

Answer:

$each \: base \: angle \: is \: of \: 50 \: \: \: 50 \: \: \: degree \\ \\ \\ \\ \\ \\ let \: the \: angles \: be \: x \: \\ the \: sum \: of \: the \: angles \: of \: a \: triangle \: = 180 \\ x + x + 80 = 180 \\ = > 2x = 180 - 80 \\ = > 2x = 100 \\ = > x = \frac{100}{2} \\ = > x = 50$
