Question

Out of a pair of complementary angles, one is 4 times of the other. find the angles.PLS TELL FAST

Answer 1

Answer:

Step-by-step explanation:

let other angle = x°

therefore, one angle = 4x°

now,

we know that sum of complementary angles is 90°

according to question

x + 4x = 90°

  5x = 90

     x = 90/5

     x = 18

therefore,

other angle = x° = 18°

one angle = 4x° = 4×18 = 72°

HOPE IT HELPS YOU

PLEASE MARK ME AS BRAINLIEST.........

Answer 2

Answer:

let x be the one angle

other angle is 4 times the first

so, other angle = 4x

since, sum of complementary angles =90°

so, x+ 4x=90

5x=90

x=18°

so other angle= 18×4

=72°
