Answer:
103 degrees
Step-by-step explanation:
The sum of the measures of all triangles is 180 degrees. The two angles given total 77 degrees. Subtracting 77 from 180 leaves 103 degrees for the 3rd angle
So the slope is 200 as he gains $200 each day
and the y intercept is 500, since he receives the $500 only once
y = 200x + 500
C the two y values repeat
The cost of the knee pad is $18.
<u>Step-by-step explanation:</u>
It is given that,
The total cost of a skates and knee pads is $63.
Therefore, Total cost = cost of skates + cost of knee pads.
We know that, the cost of the skates is $45.
<u>To find the cost of the knee pads :</u>
Let 'x' be the cost of the knee pads.
The equation is framed with the variable 'x' that gives the cost of the knee pad.
The equation is 63 = 45 + x.
<u>To find the value of x :</u>
The first step is to subtract 45 from both sides of the equation.
⇒ 63-45 = 45+x-45
⇒ 18 = x
⇒ x = 18 dollars.
The cost of the knee pad is $18.
