Question

(b) The angles are complementary and the larger is four times the smaller.
​

Answer 1

Answer:

x+4x=90

=5x=90

x=90/5

x=18

Step-by-step explanation:

we know that the complementary angle is of 90°

and in question

Given that ,

one is smaller then other then we multiply 18×4

=72

one of them is 18

and second one is 72

to check answer we add both no and answer is 90 so our answer is right

let's cheak ,

72 +18=90

Answer 2

Answer:

here is ur answer..

hope it will u!!

the angles are complementary...

means their sum is 90°

let the smaller angle be x-4.

nd the larger angle b x.

then the equation will be

x+(x-4) ≈ 90°

x+x-4 ≈ 90°

2x - 4 ≈ 90°

2x ≈ 90+4

2x ≈ 94

x ≈ 94/2

x ≈ 47°

Hence, the smaller angle is x-4 ≈ 47-4 ≈ 43°.

and the larger angle is x≈ 47°.
