Question

the ratio of measures of two complementary angles is 7:8. What is the measure of the smaller angle.

Answer 1

Answer:

42

Step-by-step explanation:

7x+8x=90

15x=90

x=6

7x=42

8x=48

third angle =90

smallest angle=42

Answer 2

Let the smaller angle be x
So, larger will be 90-x.

Given ratio 7:8.

So,
$(x )\div( 90 - x) = 7 \div 8$
8x=630-7x
15x=630
x=42
