Answer: 130
In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130
**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles

Answer:
x = -7
Step-by-step explanation:
The given equation is :
-30=5(x+1)
We need to solve the equation.
Use associative property on RHS.
-30 = 5x+5
Subtract 5 from both the sides.
-30-5 = 5x+5-5
-35 = 5x
x = -7
Hence, the value of x is -7.
Answer:
angle i, which is D)
Notice that X and I are both in the middle of the triangles.
slope is 1/3
Explanation:

We apply the slope formula:
