Answer:

X = 95 degrees

Y = 147 degrees

Z = 128 degrees

Step-by-step explanation:

Angle z can be found as : 180-52 = 128 degrees. This is because the sum of the internal angle and the external angle on the same vertex is 180°

The opposite of angle X can be found as 180-(45+50) = 85 degrees.

Now angle X lies on the same line. We can say X is exterior angles to the opposite interior angle of bigger triangle.

Angle X = 180-85 = 95 degrees

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Angle Y = 52+95 = 147 degrees.

Complete question

<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented </em>

<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a </em>

<em>variable, write an equation, and solve the problem.</em>

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16

Let the cost of green fees per person be y

If Luis and three friends went golfing, this means that 4 people went golfing.  The total cost of green fees for all of them will be $4y

If two of the friends rented clubs for $6 each, total amount spent will be $2(6)

The equation that models the statement will then be expressed as;

4y + 2(6) = 76\\

Solve for y

4y + 2(6) = 76\\4y+12 = 76\\4y = 76 - 12\\4y = 64\\y =\frac{64}{4}\\y = 16

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.

Does this graph represent a function? Why or why not?
vlabodo [156]

Answer:

A

Step-by-step explanation:

In order for a graph to be a function, it has to only cross the vertical (up and down) lines that it covers once. Since this is an angle, it crosses all the lines in two different places, and isn't a function.
