Question

25% of X degree is the supplement of 15% of 5X degree. Find X

Answer 1

Step-by-step explanation:

Let that angle be x

supplement of 140 = 180 - 140

= 40

so by the condition given in your question we get equation

80 % × x = 40

80/100 × x = 40

x = 40 × 100 /80

x = 50

so the angle is of measure 50
