Question

I need help again please and thank you :)

Answer 1

25°

Explanation:

We know the measure of a straight line is 180° . And therefore the measure of the given two co linear angles would be 180° . So ,

`\implies \rm 5x-5+2x +10=180\\`

`\implies \rm 7x +5 =180\\`

`\implies \rm 7x = 180-5 = 175\\`

`\implies \rm x =(175)/(7)= 25^o`

And we are done
