What is the measure of F?
A. 65°
B. 550
C. 75°
D. Cannot be determined

It would be 65.

Step-by-step explanation:

Because both sides are equal to 10 so they are equivalent. Which would make the angle measures equivalent to. So the angle measure would be 65.

A. 65

Step-by-step explanation:

Because two sides are 10, making the angles across the side 10 equal to one another.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
