Answer:

y=(x-1)(x-4) & 100°

Step-by-step explanation:

<u>Graph</u>

1) there are x-intercepts at 1 and 4so you set those equal to x

ex. x=1 x=4

2) then subtract them over to equal 0 and set it equal to y

ex. y=(x-1)(x-4)

<u>Angle</u>

*IMPORTANT* Straight lines are equal to 180°

∠CBD = 80°

1) So you just subtract ∠CBD from 180°

ex. 180° - 80° = 100°

We know that,

Sum of the angles in linear pair is 180°.

Given,

Angle 1 and Angle 2 are Linear Pair of Angles.

So,

Angle 1 + Angle 2 = 180°

=> 65° + Angle 2 = 180°

=> Angle 2 = 180° - 65°

=> Angle 2 = 115°

So, Angle 2 = 115°.
