Answer:
<h2>y = 6</h2>Step-by-step explanation:
The formula of a slope:
We have the slope m = 1 and the points (-4, y) and (-2, 8). Substitute:
<em>multiply both sides by 2</em>
<em>subtract 8 from both sides</em>
<em>change the signs</em>
Congruent triangles have equal corresponding sides and angles.
- The measure of the side lengths are:
,
and
- The measure of the angles are:
,
and
The given parameters are:
means that triangles DEF and GHJ are congruent triangles.
So, we have:
This gives
Also, we have:
This gives
Also, we have:
This gives
The following angles are also congruent
This gives
Also, we have:
This gives
The measure of angle J is then calculated using
This gives
Subtract 139 from both sides
