Question

If one angle of a triangle is 80 degrees and the other two angles are in the ratio 3:7.Find the measure.Of two angles

Answer 1

Step-by-step explanation:

Given, one of the angle is 80°

let the other two angles be 3x,7x

sum of all three angles =180°

80°+3x+7x=180°

10x=180-80

X= 10

therefore ,the two angles r 30°,70°
