you solve its better for yourself

Angle A = 30 degrees

Step-by-step explanation:

Using the right triangle angle sum theorem(basically, if a triangle is right, the angle measurements have to be 90, 60, and 30 degrees), we can see that angle A can only be either 60 or 30 degrees.  Angle A is narrower than angle B, so we can infer that angle A = 30 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

a is your answer
