Answer: 71 degrees.
Step-by-step explanation:
Due to the triangle being isosceles (Two sides are equal), we can assume that the angles will also be equal.
You can take 180 (The total of a triangle) and subtract by the known degree
180 - 38 = 142
Now we divide 142 by two, ONLY because this is case; both angles will be the same degree.
142 / 2 = 71
Therefore; x = 71

Answer:
D
Step-by-step explanation:
Please refer to the graph below.
So, we want to find the volume of the solid generated by revolving the green area about the x-axis.
We can use the disk method. The disk method is given by:
Where R(x) is the radius or height of the representative rectangle.
We are integrating from <em>x</em> = 0 to <em>x</em> = ln(π). The height of a representative rectangle is given by <em>y. </em>Therefore, the volume is:
Simplify:
Approximate. So, the volume of the generated solid is:
The solid is shown in the second figure.

Multiply tvs sold by cost of the warranty:
17 x 20 = $340
Subtract the total warranty from total made and divide by number of TVs.
1360 - 340 = 1020
1020/17 = 60
He earns $60 per tv
