Question

3. One of the angles of a triangle is 100 and the other two angles are equal. Find the measure of each of the equal
angles.​

Answer 1

Answer:

Each of the angles is 40°

Step-by-step explanation:

The sum of angles of a triangle is 180°

so if u angle is 100 then let each equal angle be x

As per question

100+x+x=180

2x=80

x=40

Answer 2

Answer:

40°

Step-by-step explanation:

As we know that the sum of three angles of a triangle is 180° , we will subtract 100° from 180° . After that we know that the other two angles are same, so we will divide the difference by 2. So, let us solve it :-

180° – 100° = 80°

= 80°/2 = 40°.

So, the measure of the two equal angles is 40° .
