The value x is x = 15
The three sides of the triangle are
x+10 = 25
2x-5 = 25
3x-15 = 30
==================================================
Work Shown:
The curved angle markers indicate those two angles are the same measure. The sides opposite those angles are the same length. So 2x-5 and x+10 are the same value
2x-5 = x+10
2x-x = 10+5
x = 15
Once we know x, we can find the length of each side
x+10 = 15+10 = 25
2x-5 = 2*15-5 = 30-5 = 25
This also helps confirm we have the right x value (since we got the same value for each expression)
3x-15 = 3*15-15 = 45-15 = 30
This is an isosceles triangle because exactly two sides are the same length.
(1,3)(3,5)
slope = (5-3) / (3-1) = 2/2 = 1
(3,5)(4,7)
slope = (7-5) / (4-3) = 2/1 = 2
False....they are not collinear because they have different slopes and do not lie on the same line

Answer:
The equation of the line is
, that passes through points 
Step-by-step explanation:
Given points are 
We need to write the equation of the line that passes through these points
First, we will find slope of this line

So, our slope is
. Now, we will plug the point
in the equation below.

So, the equation of the line is
.
