Answer:

Option C \frac{1}{2}(185\°-x\°)=76\°

Step-by-step explanation:

we know that

The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises

so

76\°=\frac{1}{2}(arc\ ST-arc\ XZ)

we have

arc\ ST=185\°

arc\ XZ=x\°

substitute

76\°=\frac{1}{2}(185\°-x\°)

Rewrite

\frac{1}{2}(185\°-x\°)=76\°

What is the area, in square centimeters, of the isosceles trapezoid below?
charle [14.2K]
Both triangles area:
4.2 x 8.2 = 34.44

you don’t need to divide by two cause there’s two triangles anyways.

also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)

rectangle:
4.2 x 5.3 = 22.26

the total area is 56.7cm squared

The population of a town can be modeled by P= 22,000 + 125t, where P represents the population and the t represents the number o
nlexa [21]
Given that the population can be modeled by P=22000+125t, to get the number of years after which the population will be 26000, we proceed as follows:
P=26000
substituting this in the model we get:
26000=22000+125t
solving for t we get:
t=4000/125
t=32
therefore t=32 years
This means it will take 32 years for the population to be 32 years. Thus the year in the year 2032

STatiana [176]
Factoring, you have
  h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)

The ball hits the ground when h(t) = 0, so
  0 = -16(t -4)(t +2)
  t = 4 or -2

The positive solution is the one of interest.
  It will take 4 seconds for the ball to hit the ground.
