x − 5 = 180
Add 5 to both sides

x = 185
Divide both sides by 5
x = 185 5 = 37
But it was A. 90°+m∠4
Answer:
Step-by-step explanation:
1/2(7x - 6) = 6x - 10
7/2x - 3 = 6x - 10 .....multiply by 2
7x - 6 = 12x - 20
-6 + 20 = 12x - 7x
14 = 5x
14/5 = x <===
The equation is 
<u>Explanation:</u>
We have to first find the mid-point of the segment, the formula for which is

So, the midpoint will be 
= 
It is the point at which the segment will be bisected.
Since we are finding a perpendicular bisector, we must determine what slope is perpendicular to that of the existing segment. To determine the segment's slope, we use the slope formula 
The slope is
= 
Perpendicular lines have opposite and reciprocal slopes. The opposite reciprocal of
is 
To write an equation, substitute the values in y = mx + c
WHere,
y = -1
x = 3
m = 3/2
Solving for c:

Thus, the equation becomes:

Answer:
y=4/5x + 2
Step-by-step explanation:
y=mx+b
find slope which is 8/10=4/5
choose a y and plug into problem
