Question

Find A+B+C+D=
............................

Answer 1

230

Explanation:

In a triangle, the sum of all the angles is 180 degrees, since one of the angle is given, then we can find the sum of other angles

C + D + 65 =180

C+ D = 180-65

C+D = 115

So c+

c + d = a + b

So c+d+a+b = 115 + 115

c+d+a+b = 230
