Question

Two angles of a triangle measure 30° and 25° respectively. The measure of third angle is _​

Answer 1

125° is the answer

Explanation:

• The sum of the interior angles of a triangles =180°
• Sum of two angles given = 30 + 25 = 55°
• Therefore the third angles = 180 - 55 = 125°

Answer 2

Given:-

A triangle measured 30°,25° respectively. Find the third angle.

Answer:-

30°+25°+x° = 180° [Angle sum property]

55° + x = 180°

x = 180°-55°

x = 125°

∴ The measure of the triangle is 30°,25° And 125° respectively.

∴ The triangle is a scalene triangle.
