(3, 2.5)

Step-by-step explanation:

2 points are given:

(-1,2)

and

(7,3)

The midpoint coordinate (x,y) is found by:

We sum and divide by 2, to get the average. So,

X coordinate of midpoint is:

(-1 + 7) /2 = 6/2 = 3

Y coordinate of midpoint is:

(2+3)/2 = 5/2 = 2.5

So,

Midpoint (3,2.5)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
