Answer:

∠6=78° ∠7=102° ∠14=78°

Step-by-step explanation:

Angles 6 and 7 are supplementary angles so ∠a+∠b=180°

in this case it would be 102°+x=180° and you subtract 102° from 180° getting 78°

∠7 is the vertical angles postulate stating that any angles vertical to each other are eaqual

I have this problem for hw and it’s due tomorrow. can someone please help me? (it’s y-4 not 4-4)

Answer:

All real numbers

Step-by-step explanation:

$-2(y - 4) = 20 - 2y - 12$

Start by distributing -2 inside the parentheses.

$-2y + 8 = 20 - 2y - 12$

Combine like terms on the right side of the equation.

$-2y + 8 = 8 - 2y$

Subtract 8 from both sides of the equation.

$-2y =- 2y$

Divide both sides by -2 to isolate y.

$0=0$

This is a true statement, so there are infinite solutions.
