Question

if the difference in the two complementary angles is 70 degree then the bigger angle is a)80 b)110 c)200 d)290​

Answer 1

Answer:

let angles be 'x' & 'y' and (x>y)

x-y=70(according to question) ----------[1]

x+y=90(as they are complementary angles) --------[2]

add equations 1 and 2

x-y+x+y=70+90

2x=169

x=160/2

x=80

ANSWER: a)80
