Question

two acute angles of an obtuse angled triangle whose obtuse angle measures 130° are in the ratio of 4:1. Find the angles.​

Answer 1

Step-by-step explanation:

let angles are x

130° +4x+1x= 180° (angle sum )

5x=180-130

5x= 50°

x= 50/5

x= 10

angles are :4x= 4× 10= 40°

1x= 1× 10= 10°
