Question

The sum of the measures of the angles of a triangle is 180 degrees. angels A,B,C has ratios of 3:5:7. What are their measures ?

Answer 1

Answer: A=45 B=75 C=105

Explanation:

3:5:7=180 degrees
15=180
15 divided by15=180 divided by 15
so, 1=12

so= 3:5:7 equal to (3*12) (5*12) (7*12)

A,B,C angles measures respectively = 36:60:84
if you add them (A,B,C angles) we can obtain = 36:60:84=180
(sum of the measures of the angles of a triangle is 180 degrees)

Answer 2

36:60:84

A : B : C

36° : 60° : 84°

A= 36°

B= 60°

C=84°

Explanation:

3:5:7 =15

180÷15=12

3×12=36

36:x:y =180

5×12=60

36:60:y =180

7×12=84

36:60:84 =180
