Question

find the measure x in a triangle if the measures of of the two angles is 45° and 70°​

Answer 1

Step-by-step explanation:

The sum of all the angle of a triangle is 180°

So, let the measure of the third angle be x°

ATQ,

45° and 70° are the other two angle of the triangle so,

45° + 70°+ x° = 180°

115° + x° = 180°

x° = 180° – 115° = 65°

x = 65°

Therefore, measure of x in a triangle = x = 65°

This is your freind.
