Answer:

The measure of the third angle is 35°.

Step-by-step explanation:

The sum of the three angles of a triangle is always 180°.

Let the measure of the third angle be x.

∴ 61° + 84° + x = 180°

           145 + x =180°

                    x = 180 - 145

                    x = 35°

Answer:

Step-by-step explanation:

The sum of the three angles of a triangle must always be 180⁰, so you can add the two angles that the problem gives you and then subtract this amount to 180 to get the value of the remaining angle, as follows:

1. Add up the two given angles of the triangle:

[tex]61+84=145[/tex]

2. Subtract the obtained quantity from 180⁰:

[tex]180-145=35[/tex]

Therefore the measure of the third angle is 35⁰
