Question

if one of the two complementary angle is 20 degree larger than four times the other find the angle​

Answer 1

Answer

90 degree

Step-by-step explanation:

y= 4x + 20° (according to the condition)

(x+y)° = 90 ( complimentary angle)

x+ 4x + 20° = 90°

5x +20 = 90°

5x =( 90–20)°

5x = 70°

x = 70/5

x= 14°

y = 4x + 20

y = 4*14 + 20

y = 56 + 20

y = 76°

(x+y = 14 +76 = 90° )

Answer 2

Hey mate here is your answer........

let one angle be x

and other be y

now, according to question

y = 4x - 20------1

now,

x + y = 90

x + 4x - 20 = 90 (using 1)

5x = 110

x = 22

from 1

y = 4 X 22 - 20

y = 88 - 20

y = 68

HOPE IT HELPS YOU ..............^_^
