Question

If the sum of the measure of two angles in a triangle is 125, then the measure of the third angle must be ___

Answer 1

• Sum of two angles=125°

We know in a triangle sum of angles=180°

Let the other angle be x

ATQ

`\\ \sf\longmapsto x+125=180`

`\\ \sf\longmapsto x=180-125`

`\\ \sf\longmapsto x=55°`

Answer 2

the third angle must be 55

Explanation:

a triangle must have an 180 degree angle in total

180-125=55
