Answer:
x = 6, z = 5.66 to nearest hundredth.
y = 90 degrees.
Step-by-step explanation:
From the chord intersection theorem 12*4 = 8 * x
So x = 6.
By the tangent / chord theorem:
z^2 = 2 * (12+4)
z^2 = 32
z = 5.66.
I'm not 100% sure of the value of angle y but I think its
1/2(100 + 80) = 90 degrees.
I'll try and check that out.
Yes that is right.
Answer:
A: 50
Step-by-step explanation:
because its 50$ for setup and 30 each hour for 5 hours. so 30x5=150 +50 = 200÷ nelson and 3 friends =50$ each
Since neither 5x nor -y has a "like term" in <span>2xy+xy, the sum of these quantities is simply
</span><span>2xy+xy + 5x - y = 3xy + 5x - y
You might want to write this as y(3x -1) + 5x. </span>
A regular polygon<span> is equilateral (it has equal sides) and equiangular (it has equal angles). To find the </span>area<span> of a regular </span>polygon<span>, you use an apothem — a segment that joins the </span>polygon's<span> center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).</span>
