Question

the measurement of two angles of triangle are 60 °and 80° then what is the measurement of third angle of triangle​

Answer 1

Answer:

40

Step-by-step explanation:

The sum of the interior angles of a triangle is always 180 degrees. Since you already know two of the angles, simply subtract them from 180.

180-(60+80)

=180-140

=40

Answer 2

Answer:

Let the third angle be x.

Sum of all angles of a triangle is 180°

So, 80+60+x =180°

x = 180-140

x = 40°

Therefore the measurement of the third angle be 40°.
