Answer:
<1 = 100
<2 = 80
Step-by-step explanation:
Angle 1 and angle 2 are supplementary
Supplementary angles add to 180 degrees
<1 + <2 = 180
The angles are in a ratio of 5 to 4
Multiply by x to get the measure of each angle
<1 = 5x <2 = 4x
5x+4x = 180
Combine like terms
9x = 180
Divide by 9
9x/9 =180/9
x =20
<1 = 5x = 5*20 = 100
<2 = 4x = 4*20 = 80
Answer:
m1 = 122
m2 = 58
m5 = 68
Step-by-step explanation:
m2 = 180 - 54 - 68 = 58
m1 = 180 - m2 = 180 - 58 = 122
m5 = 180 - 58 - 54 = 68
