Answer:

C) x2 + x = 306

Step-by-step explanation:

x2 + x = 306

x2 + x - 306  = 0

x2  + 18x - 17x + 18 * (-17) = 0

x ( x + 18) - 17 (x +18) =0

(x + 18) (x - 17 ) = 0

x = -18 or 17

What is the value of X ?
hjlf
Because both lines DE and XY are parallel to one another, the 115° will be same for the line segment. XY

And because XY is a flat line, it's a straight angle. Meaning it's an 180° angle.

We need to find a value of x that when added 115° will equal 180°.

We can use this equation: x + 115 = 180

Subtract both sides 115.

x + 115 - 115 = 180 - 115
x = 65

So, x is equal to 65 degrees.

Answer:

Step-by-step explanation:

1) Angle 1 and angle 2 are complementary angles. If angle 1 measures (3x + 2), what is the measure of angle 2? 3x+2 + y = 90

2) Angle A and angle b are supplementary angles. Angle A measures (2m – 10) degrees and angle b measures (m + 25) degrees. Find the measure of angle A and angle b.

3) Three angles are supplementary angles. If one angle measures 25 degrees, the second angle measures m + 15. The third angle measures 2m degrees. What is the value of m?
