Question

In ∆ ABC, Angle A=45° and Angle B=70°. Find Angle C . Briefly​

Answer 1

Answer:

we know that sum of all angles in triangle is 180 (a+b+c=180°)

Step-by-step explanation:

given

angle a is 45°

angle b is 70°

angle c be x

then 45+70+x=180

115+x=180

x=180-115

angle c (x) =65

Answer 2

Answer:

angle C = 65 degree

Step-by-step explanation:

By angle sum property ,

angle A+angle B+angle C=180 degree

=>45°+70°=180°-angle C

=>angle C= 180° -(45+70)°

=>angle C=180° -115°

thus , angle C=65°
