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

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

inverse property is the answer
