Question

Two complementary angles differ by 30 then find angles

Answer 1

Answer:

Step-by-step explanation:

Let the two angles be x,y

Given difference between angle is 30

X-Y=30. Equation1

As sum of complementary angle is 90

X+Y=90. Equation2

Add equation 1 and 2

i.e x+y=90

x-y=30

2x=120. {Using eliminate method}

X=60

For y ,substitute value of x in any one equation you will get

Y= 30

Answer 2

Answer:

two angles are a and b

a+b=90

a-b=30

Step-by-step explanation:

then a=60

b=30 .
