Question

the measure of angle of a triangle are in the ratio 5:6:7. then the smalest angle of the triangle has the measure​

Answer 1

Step-by-step explanation:

Let the common ratio be x

so....

5x+6x+7x=180 (sum of all angles of a triangle is

180°)

=>18x=180

=>x=180/18

=>x=10

so the smallest angle is 5x=5×10=50°
