Answer:

B. 16 degrees

Step-by-step explanation:

Because all of the angles in a triangle add up to 180 degrees, you can set up an equation for this problem:

2x - 10 + 4x + 46 + 3x = 180

Start by consolidating everything by adding like terms.

9x + 36 = 180

Then subtract 36 from both sides.

9x = 144

Then divide both sides by 9 to get your x.

x = 16

Part 3: Use the information provided to write the standard form equation of each circle
Ber [7]

Answer:

9. \displaystyle (x - 7)^2 + (y - 15)^2 = 25

8. \displaystyle (x - 1)^2 - (y - 10)^2 = 49

7. \displaystyle (x + 5)^2 + (y + 19)^2 = 9

Step-by-step explanation:

\displaystyle [x - h]^2 - [y - k]^2 = r^2 → Hyperbola\:Equation \\ [x - h]^2 + [y - k]^2 = r^2 → Circle\:Equation \\ [h, k] → Centre

According to the equations in the exercises, in the parentheses, ALL NEGATIVE SIGNS give the OPPOSITE terms of what they REALLY are, so be EXTREMELY CAREFUL with your translations:

9. [4, 11]

+ 3 + 4

_____

[7, 15] → (x - 7)² and (y - 15)²

8. [−2, 8]

+ 3 + 2

_____

[1, 10] → (x - 1)² and (y - 10)²

7. [−8, −14]

+ 3 - 5

______

[−5, −19] → (x + 5)² and (y + 19)²

** NOTISE THAT THE RADII <em>NEVER</em><em> </em>ALTER.

I am joyous to assist you anytime.
