Question

How to solve this question.

Answer 1

We know: The sum of measures of angles in the triangle is equal 180°.

x - the measure of the second angle

2x - the measure of the first angle

x - 8° - the measure of the third angle

The equation:

`2x+x+x-8=180\\\\4x-8=180\ \ \ \ |+8\\\\4x=188\ \ \ \ |:4\\\\x=47`

Answer:

`2x=2\cdot47^o=94^o\\\\x=47^o\\\\x-8^o=47^o-8^o=39^o`
