Answer:
Part a) 3x + x + 48 = 180
Part b) m<1 = 99
m<2 = 81
Explanation:
For part a) it is very important to note that all angles on a straight line equals to 180 degrees, so, we can make angle measure 1 and 2 equal to 180 degrees using the values given:
3x + x + 48 = 180
For part b, we have to solve the equation we made in part a to solve for x:
3x + x + 48 = 180
4x + 48 = 180
4x = 132
x = 33
Now we find the angle measure by putting the x value into each of the expressions given:
m<1 = 3x
m<1 = 3(33)
m<1 = 99
--------------------
m<2 = (x + 48)
m<2 = (33 + 48)
m<2 = 81
