Question

angle a and angle b are complementary angles . angle a = (x + 10)° and angle b = (2x-10)° find angle a and angle b.​

Answer 1

Answer:

sum of two complementary angles = 90°

then.. a+b= 90°

(x+10)° + (2x-10)°= 90°

x+2x+ 90- 10+10

3x+90

x= 90/30

x= 30°

angle a = 30°+10°=40°

angle b =2×30°- 10°

=60°-10°=50°

check : angle a + angle b = 90°

40°+50°=90°

problem solved...☺☺☺

hope it will help u dear..

Answer 2

Answer:

angle a=(x+10)°

angle b=(2x-10)°

angle a+angle b=90°

x+10+2x-10=90

3x=90

x=90/3

x=30°

angle a=x+10=30+10=40°

angle b=2x-10=2×30-10=60-10=50°.
