<u>Answer:</u>
angle a =
<u>Step-by-step explanation:</u>
The angles in a triangle add up to 180°.
∴ ∠a + 13° + 13° = 180°
⇒ ∠a + 26° = 180°
⇒ ∠a = 180° - 26°
⇒ ∠a = 154°
This is how you add fractions..

Answer: D. (-2,0) and (9,0)
Step-by-step explanation:
When you equate the factors to 0 you get
(X+2) = 0
X = -2
(X-9) = 0
X= 9
Here the Y value is 0 as you find the factors of x when the Y value is 0.
So the answer is (-2,0) and (9,0)
