Question

*The two angles of a triangle are 40° and 60° respectively, so what is the measure of the remaining angle?*

1️⃣ 100°
2️⃣ 80°
3️⃣ 60°
4️⃣ 140°​

Answer 1

Answer:

80degree

Step-by-step explanation:

A+B+C=180°

40+60+C=180°

100+C=180°

C=180-100

C=80°

Answer 2

Given : The two angles of a triangle are 40° and 60° respectively,

To Find :  the measure of the remaining angle

1️⃣ 100°

2️⃣ 80°

3️⃣ 60°

4️⃣ 140°​

Solution:

Sum of angles of a triangle is 180°

Two angles are given  40° and 60°

Let say third angle is X

Add all the angles and equate with 180°

=>  40° +  60°  + X  = 180°

=>100°  + X  = 180°

=>X  = 180° - 100°  

=>X  =  80°

Option 2 is correct

measure of the remaining angle  is    80°
