Answer:
v = -7.5
Step-by-step explanation:
Step 1: Subtract 3v from both sides.
v-17 − 3v = 3v−2 −3v
−2v−17=−2
Step 2: Add 17 to both sides.
−2v−17+17=−2+17
−2v=15
Step 3: Divide both sides by -2.
-2v/2 = 15/2
v = -15/2
v = -7.5

Answer:
D.
Step-by-step explanation:
Complementary angles are two angles whose measures add to 90°.
A.
m<CFD = 150° - 100° = 50°
m<EFD = 180° - 150° = 30°
Sum = 80°
No
B.
m<AFB = 40°
m<DFE = m<EFD = 30°
Sum = 70°
No
C.
m<AFC = 100°
Sum > 100°
No
D.
m<BFC = 100° - 40° = 60°
m<DFE = 30°
Sum = 90°
Yes
Answer: D.
Answer:
<u>1260 degrees (1260°)</u>
Step-by-step explanation:
<u>Formula to Find Sum of Interior Angles of a Polygon</u>
- 180 (n - 2)
- n is the <u>number of sides</u> of the polygon
<u>Nonagon (9-sided polygon)</u>
- 180 (9 - 2)
- 180 × 7
- <u>1260 degrees (1260°)</u>
