What is the value of x?
Pavlova-9 [17]

Answer:

x = 8

Step-by-step explanation:

Add the four angles given to get 264°

Subtract 264° from the total measure of angles in the pentagram (360°) which gives you 96° for the missing angle measure. From there, it's just basic algebra.

x = 96 ÷ 12

x = 8

A benefit concert is being held at a nearby venue that charges $500 for rental of the space. Additionally, they are charging $5
sertanlavr [38]

8 is the answer. Because if you multiply 5 x 3, its 15, so that gives you the 15 dollar ticket price, and add the 5 that didnt need to pay, wich is 5 + 3 = 8.

Have a great day, and sorry if i got it wrong. <3

AB, CD, and EF intersect at O. If CD is perpendicular to EF and m
REY [17]

Answer:

m(∠AOF) = 148°

Step-by-step explanation:

From the figure attached,

CD intersects line EF at a point O.

Line CD is perpendicular to the line EF.

m(∠AOE) = 32°

m(∠COE) = 90°

Since m(∠COE) = m(∠AOE) + m(∠AOC) = 90°

32° + m(∠AOC) = 90°

m(∠AOC) = 90° - 32° = 58°

m(∠AOF) = m(∠AOC) + m(∠COF)

               = 58° + 90°

               = 148°

Therefore, m(∠AOF) = 148° will be the answer.
