The measure of an angle is nine times the measure of its complementary angle. what is the measure of each angle?

Step-by-step explanation:

for complementary angles, a+b = 90deg

for this question, a = 9b

=> 9b + b = 90deg

b = 9deg

=> a = 9b = 81deg

can someone answer this question plz

step-by-step explanation:

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
