Answer:
Explanation:
The three angles in a triangle add up to 180 :
If angle 1 is 90 because it is a right angle triangle then :
Angle 2 + Angle 3 = 180 -90
Angle 2 + Angle 3 = 90
The ratio of Angle 2:Angle 3 is 1:2
There are 3 shares in total (1+2=3)
1 share = 90 ÷ 3 = 30
So Angle 2 is 30 and angle 3 is 60
Hope this helped and have a good day
