Answer:
Step-by-step explanation:
Remember that the angle sum of a triangle = 180 degrees.
If we know that the ratio of angles are 2:3:5
You can say
Angle 1 = 2 parts
Angle 2 = 3 parts
Angle 3 = 5 parts
We can say that each part must be equal.
That means in total we have 2 + 3 + 5 = 10 parts.
Find how big the angle is for each part.
10 parts = 180 degrees
1 part = 18 degrees.
So since we know :
Angle 1 = 2 parts , Angle 1 = 2 times 18 = 36 degrees
Angle 2 = 3 parts , Angle 2 = 3 times 18 = 54 degrees
Angle 3 = 5 parts, Angle 3 = 5 times 18 = 90 degrees
So the largest angle of the triangle (Angle 3) must be 90 degrees.
