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.
