Answer:

Step-by-step explanation:
A triangle adds up to 180.
180 - 50 = 130
Since both of the missing angles are congruent each of the missing angles is 65 degrees.
130/2 = 65
As per the exterior angle theorem, the measure of the exterior angle is determined by the sum of the opposite interior angles.
65 + 65 = 130
So, the measure of

Option D.) a reflection over the y-axis and then a translation down by 5 units.
Answer:
f(x) = x² + 2x - 3
(x+3)(x-1)
Step-by-step explanation:
Zeroes are -3 and 1
Let α = -3 and β = 1
f(x) = x² - (α+β)x + (αβ)
= x² - (-3+1)x + (-3 × 1)
= x² - (-2)x + (-3)
= x² + 2x - 3
x²+2x-3
x² - x + 3x - 3
x(x-1) + 3(x-1)
(x+3)(x-1)
