Question

find the value of x for which the angle (2x-5) degree and (x-10) degree are the complementary angle

Answer 1

if they are complementary angle then the sum of them will 90°.
thus,
(2x-5)° + (x-10)° =90°
2x-5+x-10=90°
3x-15=90°
3x=90+15
3x=105
x=105÷3
x=35°. ans

Answer 2

if these 2 angles are complimentary then
(2x-5 )+ (x-10) = 90
=>3x -15= 90
=>3x=90+15
=>3x=105
=>x=105/3
=>x=35

here is your ans
