Does anyone know this answer???​

Answer 1

part a) 5x + x - 12 = 180

part b) m<1 = 20

m<2 = 160

Explanation:

For part a, it is important to note that all angles on a straight line equals to 180 degrees. So, with the expressions given, we can make this equation:

5x + x - 12 = 180

For part b, we have to first solve for x using the expression we made for part a, then use the x value to find the angle measures:

5x + x - 12 = 180

6x - 12 = 180

6x = 192

x = 32

m<1 = x - 12

m<1 = 32 - 12

m<1 = 20

m<2 = 5x

m<2 = 5(32)

m<2 = 160
