Question

find the value of x for which the angle (12x-5)⁰ and (x-10) are the complementary angle
​

Answer 1

Answer:

(12x-5)° +(x-10)°=90°

12x-5+x-10=90

13x-15=90

13x=90-15

x= 75/13

Answer 2

Answer:

When the sum of two angles is 90 then the angle is complementary angle

(12x-5)+(x-10)=90

12x-5+x-10=90

12x+x-5-10=90

13x-15=90

13x=90-15

13x=75

x=75/13
