The measure of an angle is five times the measure of its supplementary angle. what is the measure of each angle?

Step-by-step explanation:

for supplementary angles, a+b = 180deg

for this question a is 5 times b

=> 5b + b = 180deg

b = 30deg

=> a = 5b = 150deg

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
