Answer:

11.25 degrees

Explanation:

Two complementary angles are angles that both add to 90deg.

x = angle 1

y = complementary angle

x = 7×y

And

x + y = 90deg

So

7×y + y = 90deg

8×y = 90deg

y = 90deg / 8

y = 11.25deg

((And x = 78.75deg, but they don't ask for that.))

Answer:

11.25°

Explanation:

Let s represent the smaller angle. Complementary angles have a sum of 90°, so we have ...

s + 7s = 90°

8s = 90° . . . . . collect terms

s = 11.25° . . . . . divide both sides by 8

The smaller angle is 11.25°.

Check

The larger angle is 7(11.25°) = 78.75°.

11.25° +78.75° = 90° . . . . as required
