What is the value of x? (5 points) select one: a. 20 b. 40 c. 45 d. 85

x is equal to 40

Step-by-step explanation:

Since the two angles together equal 90, we can add them together and solve for x.

10 + 2x = 90

2x = 80

x = 40

x = 40

The angle is a right angle, which = 90 degrees.

2 x 40 = 80

80 + 10 = 90

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
