Answer:
Two extraneous solutions
Step-by-step explanation:
We use the profit concept, and doing this, it is found that if 150 televisions are sold, the profit is $50,700.
-------------------------------------------
Profit is given by revenue subtracted by cost.
In this question:
- Revenue:

- Cost:

Thus, the profit of selling x televisions is:




-------------------------------------------
For 150 televisions, we have P(150), so:

If 150 televisions are sold, the profit is $50,700.

Answer:
the second one and third one
Step-by-step explanation:
The angle measure of a straight line is 180°, and so if the you know that one angle off of it is (5x)°, then you know that the other section is (180 - 5x)°.
Because it's an isosceles triangle, there are two identical angles, which happen to be the angles with the measure of (5x - 30)° and (180 - 5x)°.
Since they have the same measure, 5x - 30 = 180 - 5x. Solve:

Thus,
x = 21°.
