Step-by-step explanation:
Answer:
∠8 = 40°, ∠6 = 50°, ∠9= 140°
Step-by-step explanation:
∠8 = 40° (vertically opposite angles are congruent)
now, using angle sum property of triangles
∠6 + 90° + 40° = 180°
∠6 = 180° - 130°
∠6 = 50°
and, using exterior angle property,
50° + 90° = ∠9 = 140°
A negative slope can be illustrated when a line that is trending downward from left to right, has a negative value.
<h3>What is a negative slope</h3>
It should be noted that a negative slope implies that two variables are negatively related.
This implies that when x increases, y decreases, and also when x decreases, y increases.
Graphically, a negative slope implies that as the line on the line graph moves from left to right, the line will fall.

No it is not. It is a fraction
