• y is vertically opposite to the one whose measure is 43º.
So,
y = 43º.
• x and y are supplementary angles:
x + y = 180º
x = 180º <span>– y
x = 180º </span><span>– 43º
x = 137</span><span>º.
</span><span>• z and x are vertically opposites.
So,
z = x
z = 137º<span> <</span></span>——<span><span>— this is the answer.</span>
I hope this helps. =)

The first one. A is the answer
Step-by-step explanation:
Given point (4 , -8) , slope (m) = 2
Now
the equation of line is
y - y1 = m ( x - x1)
y +8 = 2 ( x -4)
y + 8 = 2x - 8
2x - 8 - 8 -y = 0
2x - y - 16 = 0
which is the required equation
Answer: 2/5 of a pizza for for $6 offers the best deal.
Step-by-step explanation:
Pizzas are sold by fraction at Arnold's Pizzeria.
1)You can buy 1/6 of a pizza for $2.75. This means that the cost of a full pizza at this rate would be
6 × 2.75 = $16.5
2) 2/5 of a pizza for for $6, This means that the cost of a full pizza at this rate would be
6 × 5/2 = $15
3) 1/2 of a pizza for $8. This means that the cost of a full pizza at this rate would be 8 × 2 = $16
4) 2/3 of a pizza for $12. This means that the cost of a full pizza at this rate would be 12 × 3/2 = $18
Therefore, the best deal is 2/5 of a pizza for for $6
