Answer:

∠2 = 78°

Step-by-step explanation:

Angle of a straight line is 180°.

So, that would mean ∠1 + ∠2 = 180°.

⇒ ∠2 = 180° - ∠1

⇒ ∠2 = 180° - 102°

⇒ ∠2 = 78°

Hence, the answer.

Solve the equation 13-2x=-7

patriot [66]

Subtract 13 from both sides.

-13
-7 = -20

-2x = -20

Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.

-2/-2 = 1
-20/-2 = 10

Your answer:
x = 10
