Question

Find the measures of an angle which is 36° more than four fifth of its supplement

Answer 1

Answer:

$x = \frac{1}{5}(90 - x) + 36$

$5x = 90 - x + 180$

$6x = 270$

$x = \frac{270}{6} = 45$

Answer 2

Answer:

x=100°

Step-by-step explanation:

let the angle be x

therefore it's supplement = (180-x)

now, according to the condition

x = 4/5 ×(180-x)+36

x = (780 - 4x +180)÷5

5x+4x =900

9x=900

therefore, x=100
