Question

In the given fig, BD IICE; AC = BC, angle ABD=20° and angle ECF=70°. Find angle GAC.​

Answer 1

Answer: -35

Step-by-step explanation:

we will suppose angle BCF and angle GCA x

we will suppose angle CBD y

x + x +70 = 180 (sum of angles on a straight line = 180)

2x + 70= 180

2x=i80 - 70

x= 110/2 (the slash is divide sign)

x= 55

the above is the answer of angle GCA and angle BCF

y=180 - 20

y=160

the above is the answer for angle CBD

GAC=55 + 160=180 (sum of a triangle = 180)

GAC=215=180

GAC= -215+180

GAC= -35
