Find the value of x.
.
102
3x
(y + 710
78
39
32
O 13

x=13

Step-by-step explanation:

For isosceles triangle the bottom angles are equal to each other.

and for all triangle the sum of the angles is 180.

180(the sum of the angles)-102(the top angle)=78

78÷2=39

3x=39

3x=39

(divide 3 for both sides)

x=13

extra information:

y+7=39

y=32
