It's been a while since i learned this..
Hi Bre,
Since lines a and b are parallel, we know that in the image:
- ∡1 ⇔ ∡5
- ∡2 ⇔ ∡6
- ...
- ∡4 ⇔ ∡8
We're given the angle of ∡7, which is 114°. We can see that ∡7 + ∡8 will equal to 180° (since line b is a straight line) and since ∡8 ⇔ ∡4, we can deduct that ∡7 + ∡4 = 180°.
From here, it's just imputing the information and solving.
⇒ 114° + ∡4 = 180°
⇒ ∡4 = 180° - 114°
⇒ ∡4 = 66°
-Hope this helps!
Answer:
The answer to your question is (x + 3)² + (y + 6)² = 2
Step-by-step explanation:
Endpoints (-4, -7) and (-2, -5)
Process
1.- Find the length of the radius
d = 
d = 
d = 
d = 
d = 
Radius =
= 
2.- Find the center
Xm = 
Ym = 
Center = (-3, -6)
3.- Write the equation
(x - h)² + (y - k)² = r²
(x + 3)² + (y + 6)² = (
)²
(x + 3)² + (y + 6)² = 2

Answer:
x = 8
Step-by-step explanation:
Given
- x = - 8 ( multiply both sides by - 1
- x × - 1 = - 8 × - 1, that is
x = 8
