Question

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

Answer 1

Step-by-step explanation:

given that

Angle 1 - 80

remaining angle measure

= 180-80

= 100

ratio of remaining angles is

2:8

2x + 8x = 100

10x = 100

x = 100/10

x = 10

therefore other angles are

2x = 2 × 10 = 20°

8x = 8 × 10 = 80°
