Answer:

∠2 = 152

Step-by-step explanation:

A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.

That means that 180-28, will give us our other angle.

Answer:

152°

Step-by-step explanation:

Angles on a straight line add up to 180°

Angle 2 + 28 = 180

Angle 2 = 180 - 28

= 152°

KIM [24]

/Answer:

Short Answer Type:

P1 - (-2,8)

P2 - (1,1)

Slope: (1 - 8) / (1 + 2)

=> -7/3

Therefore: 1 = -7/3 + c

=> 10/3 = c

<h2><u>Therefore equation: y = -7x/3 + 10/3</u> </h2>
