-x-=+ negative times a negative is a positive
The angle based on the information given about the rail is 163°.
<h3>How to illustrate the information?</h3>
From the information given, the value of angle 2 will be:
17° + x = 180° (angle on a straight line)
Collect like terms
x = 180° - 17°
x = 163°
In this case, it should be noted that angle 1 and 2 are alternate angles. Therefore, angle 1 will be 163°.

Answer:

Step-by-step explanation:
We'll write the polynomial using only the roots required to simplify calculations. However, it states the final answer should not have a radical or complex number in. Therefore, we need to rid them:

Expanding this, we get:
.
The answer is -.25 4(-.25) = -1 +6 = 5! Hope this helps!!! :)
Answer:
(x-10)^2 + (y-2)^2 = 49
Step-by-step explanation:
I'm assuming that 10-2 means (10,2)
Equation of circle:
(x-a)^2 + (y-b)^2 = r^2
Plugging in the values that we know:
(x-10)^2 + (y-2)^2 = 7^2
(x-10)^2 + (y-2)^2 = 49
Hope this helps!
