Question

If the two angles of a triangle are 80° and 60° .find the third angle​

Answer 1

40 degrees

Explanation:

To find the measure of the third angle in a triangle when you know the measures of two angles, you can use the fact that the sum of the angles in any triangle is always 180 degrees.

Let A, B, and C represent the measures of the angles in the triangle.

Given angles:

Angle A = 80 degrees

Angle B = 60 degrees

Now, you can find the measure of the third angle (Angle C) using the following equation:

Angle C = 180 degrees - (Angle A + Angle B)

Angle C = 180 degrees - (80 degrees + 60 degrees)

Angle C = 180 degrees - 140 degrees

Angle C = 40 degrees

So, the measure of the third angle (Angle C) is 40 degrees.
