If you're solving for a, you would add 32 to both sides
2a=32
then you would divide by 2
a=16

Z1 and Z2 are vertical angles. Z2 has measure of 93° what is the measure of Z1? enter your answer in the box.

Soloha48 [4]

Answer:

m∠Z1 = 93°

Step-by-step explanation:

Vertical Angles are the angles opposite each other when two lines cross.

They are congruent (the same as each other).

Therefore, m∠Z1 = m∠Z2, so if m∠Z2 = 93° then m∠Z1 = 93°

The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide a pin drop near one focus can clearly be

dedylja [7]

Answer:

Let the coordinate of focus be $(\pm c , 0)$

As per the statement: The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide.

⇒Length of Major axis=base of an auditorium = 200 feet and Length of a minor axis=wide of a auditorium = 100 ft

Semi-major axis (a) = 100 ft and

semi-minor axis(b) = 50 ft

Then, by an equation:

$c^2 = a^2-b^2$

Solve for c:

Substitute the given values we have;

$c^2=(100)^2-(50)^2$

Simplify:

$c^2 = 7500$

$c=\sqrt{7500} = 86.6025404$ ft

Distance between the foci is, $2c = 2 \cdot 86.6025404 = 173.205081$

Therefore, the distance between the foci to the nearest 10th of a foot is, 173.2 ft

$\bf 2\frac{1}{2}\left( 8x-\cfrac{4}{5} \right)=-62\implies \cfrac{5}{2}\left( 8x-\cfrac{4}{5} \right)=-62\implies \stackrel{\textit{distributing}}{\cfrac{5\cdot 8}{2}x-\cfrac{5\cdot 4}{2\cdot 5}}=-62 \\\\\\ 20x-2=-62\implies 20x=-60\implies x=\cfrac{-60}{20}\implies x=-3$
