Question

The measure of two angles of a triangle are 60° and 40°. Find the third angle.

Answer 1

hey there
as you know that asp of triangle is 180 degree
so to find 3 rd angle the equation will be
180-(60+40)
180-100
80 degree is the measure of third angle

hope it was easy 
thanks

Answer 2

Hlo friend.. Cutiepie Here

Here is ur answer :

Triangle has three angles.

Ist angle = 60

IInd angle = 40

The sum of all the internal angles of a triangle is 180.

Let the third angle be x.

➡️60 + 40 + x = 180

➡️100 + x = 180

➡️x = 180 - 100

➡️x = 80

Therefore, the third angle is 80°.

HOPE IT HELPS YOU..
