What is the value of x?

Step-by-step explanation:

Notice that this is an isosceles triangle, so the angles opposite to the sides of equal length (40 units) must be equal. That means that angleD = angleE

Then using the rule for addition of interior angles of a triangle equal to 180, we can write:

angleD + angleE + angleF = 180 degrees

x + x + 95 = 180

2 x = 180-95

2 x = 85

x = 85/ 2

x = 42.5 degrees

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
