Lines e and f are parallel. The m<9=80° and m<5=55°. Which angle measures are correct? Check all that apply.
Answers
Answer with explanation:
m∠9=80°
m∠5=55°
⇒∠3+∠5=180°----[e║f, and these angles are on the same side of transversal c]
→∠3+55°=180°
→∠3=180° -55°
→∠3=125°
→∠3=∠2-----[Vertically Opposite Angles]
1→→∠2=125°-----[True]
2.→→∠3=55°-----[False]
3.→→∠5=∠8=55°-----[Vertically Opposite Angles]----[True]
4.→→m∠9=m∠12=80°
m∠12=100°-----[false]
5.→→∠12 +∠14=180°-----[Lines e and f are parallel, and d is a transversal.]
→→80°+∠14=180°
→→∠14=180°-80°
→→∠14=80°------[True]
6.→→∠14 +∠16=180°----[Interior Angles on the same side of transversal]
→100°+m∠16=180°
→m∠16=80°-----[True]
→→→1,3,5 and 6 are Correct.

This question is incomplete. Hereis the complete question:
Which of the following options have the same value as 65% of 20?
(A) 0.65⋅20 (B) 65/100 divided by 20 (C) 65/20 * 100 (D) 65 * 20
Answer:
The correct answer is option (A) 0.65⋅20
Step-by-step explanation:
In this case they are asking us for an expression that is equivalent to 65% of 20. They are not asking us what is the value of that operation.
When we do a percentage calculation we can do it in two ways.
Let's see each one of them:
. (65 * 20): 100 =
1300: 100 = 13
. 0.65. 20 = 13
As we can see both ways we get the same result.
Given this information we can say that the correct answer is option A.
Answer:
13
Step-by-step explanation:

Answers
The answer is B.
80%*x=96
x=96/80%
x=120
then 25% of 120 is your answer to find this half 120 twice
half 120=60
half 60=30
Therefore 30 is the answer which is B

B = area of the base of the triangles
Area of the triangle = hb/2 = (8ft * 5ft)/2 = 40ft² / 2 = 20 ft²
V = 20 ft² * 4 ft = 80 ft³
Volume of the triangular prism is 80 ft³
