We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
7x-99=2x+1
5x-99=1
5x=100
x =  \frac{100}{5} = 20

So, your answer is 20°.

5(1 + 4m) – 2m = -13
Oksana_A [137]

Answer and Step-by-step explanation:

Solve for m.

<u>First, distribute the 5.</u>

5 + 20m - 2m = -13

<u>Combine like terms.</u>

5 + 18m = -13

<u>Subtract 5 from both sides of the equation.</u>

18m = -18

<u>Divide by 18 to both sides of the equation.</u>

<u>m = -1 <- This is the answer.</u>

12.<br> What is the<br> equation of a circle with center (-7, -3) and radius 2?
Genrish500 [490]

Answer:

(x + 7)^2 + (y + 3)^2 = 4

Step-by-step explanation:

The standard equation of a circle is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. We can substitute the information given to obtain:

(x + 7)^2 + (y + 3)^2 = 4

The midpoint of AB is M (0, -3). If the coordinates of AA are (2, 1) what are the coordinates of BB?
frez [133]

Answer:

B(-2, -7)

Step-by-step explanation:

Midpoint is (0, -3)

A(x₁, y₁) B(x₂, y₂)

A(2, 1)

Midpoint = (\frac{x_{1} + x_{2} }{2}, \frac{y_{1} + y_{2} }{2} )\\\\Midpoint = (\frac{2+ x_{2} }{2}, \frac{1 + y_{2} }{2} )

(0, -3) = (\frac{2+ x_{2} }{2}, \frac{1 + y_{2} }{2} )

              \frac{2+ x_{2} }{2} = 0\\\\2 + x_{2} = 0\ \ \ \ times\ both\ sides\ by\ 2\\x_{2} = -2\ \ \ \ subtract\ both\ sides\ by\ 2

              \frac{1 + y_{2} }{2} = -3\\\\1 + y_{2} = -6\ \ \ \ times\ both\ sides\ by\ 2\\y_{2} = -7\ \ \ \ subtract\ both\ sides\ by\ 1

∴ B(-2, -7)
