Hey Please help me x

Answers

Answer:

x = 20

Step-by-step explanation:

4x and 5x are same- side interior angles and sum to 180° , then

4x + 5x = 180

9x = 180 ( divide both sides by 9 )

x = 20

Answer:

x = 20

Step-by-step explanation:

the two angles are same-side interior angles, thus, the two angles add up to 180°

=> 4x + 5x = 180

=> 9x = 180

=> x = 20

List the angles in order from largest to smallest

Answers

Answer:

a line segment has endpoints P(-1,5)and Q(5,2) find the coordinate of that trisect the segment​

Answers

Answer:

(1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

Step-by-step explanation:

Moving from P to Q, we see that x increases by 6  and y increases by 3.

"Trisect" means "divide into three equal subintervals."

We find (1/3) of 6 (which comes out to 2) and (1/3) of 3 (which comes out to 1).  

Thus, the first junction (between 1st and 2nd trisection) is (-1 + 2, 5 + 1), or (1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)
