45 degrees

Step-by-step explanation:

We know that angle 4 equals angle 2 because corresponding angles are congruent.

So x+30 = 2x+15,

We subtract 15 from both sides,

x + 30 - 15 = 2x + 15 - 15

x + 15 = 2x

Now we subtract x from both sides,

x - x + 15 = 2x - x

15 = x

x = 15 degrees

So we plug this in angle 4,

15 + 30 = 45 degrees

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2
