Question

a)Find X and the sum of a+b+c+d in the following figure.​

Answer 1

Answer:

105 + 75 + 60 + X = 360

240 + X = 360

X = 120

Step-by-step explanation:

1) 60 + A = 180

A = 120

2) 120 + B = 180

B = 60

3) 105 + C = 180

C = 75

4) 75 + D = 180

D = 105

A + B + C + D = 120 + 60 + 75 + 105 = 360
