Question

if (3x-9) and (x-1) are complementary angles then find angle class 9

Answer 1

Answer:

complementary angle =90

3x -9 + x-1 =90

4x -10 =90

4x = 90+10

4x = 100

x =100/4

x = 25

so, first angle

3x - 9 = 66

and second angle

x-1 = 24

hope its help

Answer 2

Answer:

(3x-9)+(x-1)=90

4x-10=90

4x=90+10

x=100/4

x=25

hence,3x-9=3(25)-9

=75-9

=66°

x-1=25-1

=24
