Question

I need help with this one

Answer 1

x = 82.5

Explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + x - 45 + 60 = 180, that is

2x + 15 = 180 ( subtract 15 from both sides )

2x = 165 ( divide both sides by 2 )

x = 82.5

Answer 2

--------------------------------------------------

Explanation:

60+x-45+x=180

60-45+2x=180

15+2x=180

2x=180-15

2x=165

x=165/2

x=82.5
