Answer:
18
Step-by-step explanation:
angels in a triangle add up to 180
180-(82+80)= x
x = 180 - 162
x = 18
Answer:
- no real solutions
- 2 complex solutions
Step-by-step explanation:
The equation can be rearranged to vertex form:
x^2 -4x = -5 . . . . . . . . . subtract 4x
x^2 -4x +4 = -5 +4 . . . . add 4
(x -2)^2 = -1 . . . . . . . . . show the left side as a square
x -2 = ±√-1 = ±i . . . . . . take the square root; the right side is imaginary
x = 2 ± i . . . . . . . . . . . . . add 2. These are the complex solutions.

<em>Comment on the question</em>
Every 2nd degree polynomial equation has two solutions. They may be real, complex, or (real and) identical. That is, there may be 0, 1, or 2 real solutions. This equation has 0 real solutions, because they are both complex.
If every capsule requires 0.007 grams of aspirin, and the druggist has 14 grams, the best way to determine how many capsules he has is to divide 14 grams by 0.007
. This means that he can make C. 2,000 capsules
