Answer:
1 < a < 13/5
Step-by-step explanation:
2 < 2a - 3(1 -a) < 10
2 < 2a - 3 + 3a < 10
2 < 5a - 3 < 10
2 + 3 < 5a - 3 + 3 < 10 + 3
5 < 5a < 13
5/5 < 5a/5 < 13/5
1 < a < 13/5

Answer:
no angle c is not supplementary
Step-by-step explanation:
Angle A and angle B are supplementary
A+B=180° Equation 1
The measure of angle B is equal to four times the complement of angle A
The complement of angle A=90°-A
B=4(90°-A)
B=360°-4A
Substitute the value of B in equation 1
A+360°-4A=180°
-3A=-180°
A=60°
The measure of angle A=60°
B=360°-4A=360°-4(60°)=120°
The measure of angle B=120°
