Question

find the measures of the angles of a triangle if one angle is 80° and the other 2 angles are in the ratio of 2:8​

Answer 1

Step-by-step explanation:

let 2x and 8x be the other two angles

total angle of a ∆=180°

2x+8x+80°= 180°

10x= 180°-100°

x= 100/10= 10°

therefore the other two angles are

2x= 2×10= 20°

and 8x= 8×10 = 80°
