Question

In a triangle abc angle A=45 degree and Angle B = 70 degree find the angle C. ​

Answer 1

Answer:

Angle C = 65 degree

Step-by-step explanation:

Angle A = 45 degree

Angle B = 70 Degree

Sum of all the angles in Triangle ABC = 180 degree.

Angle A + Angle B + Angle C = Triangle ABC

45 degree + 70 degree + Angle C = 180 degree

115 degree + Angle C = 180 degree

Angle C = (180-115) degree

Angle C = 65 degree

Answer 2

Answer:

C= 65 degree

Step-by-step explanation:

One of the properties of triangles are that the sum of all interior angles of a triangle is 180 degree, so we can solve the problem like this:-

45 + 70 + x = 180

115 + x = 180

x = 180 - 115 (Transposition rule - '+' when transposed to the other side becomes '-' )

x = 65

We can check the answer by adding all the 3 angles of the triangle, that is '45 + 70 + 65' if the answer comes 180, the answer is right so:-

45 + 70 + 65 = 160

Therefore we can conclude that Angle C= 65
