Answer:

x=70°

y=30°

z=20°

Step-by-step explanation:

You first need to find y, which would be 30 because the sum of the first two angles is 150, and a triangle has 180 degrees, so 180-150=30.

By finding y, we can now find a, because if you take the entire triangle, y+z must equal 50. So, z=20 because 30+z=50.

And finally, we can find x to be 70 since the sum of the two other angles is 110 and 180-110=70.

<h2>Complete Question: </h2>

The energy usage of a light bulb is a function. The input for the function is ___, measured in hours. The output of the function is energy usage, measured in _____. Identify the functional relationship between the variables. ________ is a function of __________. The graph of the function will show energy usage on the ________ axis and time on the _______ axis.

Input is time.
Output is measured in kilowatts.
Energy usage measured in kilowatts is a function of time measured in hours.

The graph representing the function will show:

energy usage (kilowatts) on the y-axis
time (hours) on the x-axis.

A light bulb as a function expends energy which is measured in kilowatts and it is dependent on time measured in hours.

This implies that, the amount of energy usage of the light bulb is determined by the number of hours the light bulb is turned on.

Thus, energy usage of the light bulb (kilowatts) is a function of time (hours).

Graphing the function, we would plot the input (time) on the x-axis, against (output) energy usage on the y-axis.

Therefore,

Input = time (hours) - plotted on the x-axis.

Output = energy usage (kilowatts) - plotted on the y-axis.
