Answer:

Step-by-step explanation:

The definition of one radian is "a unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius." So, on the unit circle, because the radius is one, one radian's arc length is also one. Basically, on the unit circle, the radian measure of an angle is equal to the arc length is makes.

Trig Functions are just the coordinates on the unit circle plotted on to a graph. Think about it this way, if you pin a point on the unit circle and spin the circle, the point will go up and down and up and down forever (if there is no friction). This is the same thing with trig functions. They repeat them selves over and over again. In an actual triangle, we can't get angles more than 180 degrees, but because the trig functions go on forever, we can virtually plug in any angle degrees we want and produce an answer. The unit circle help us understand that some angles are just other angles written in another way, like 90 degrees and 450 degrees are actually the same thing.

Trevor has two fraction models, each divided into equal-sized sections. The
erma4kov [3.2K]

Answer:

I will answer in a general way because the options are not given.

We know that the area of model A is smaller than the area of model B.

For model A, we have 72 shaded sections, out of 100.

Then the quotient of model A is:

72/100 = 0.72

For model B we have 10 sections, and x shaded ones.

Because model B is greater than model A, we know that:

x/10 should be larger than 72/100

then we have the inequality:

x/10 > 0.72

x > 0.72*10

x > 7.2

And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:

10 ≥ x > 7.2

Then x can be any whole number in that interval.

the possible values of x are:

x = 8

x = 9

x = 10

Does 24,7 and 26 make a right triangle
makvit [3.9K]

Answer:

no it doesn't

Step-by-step explanation:

Use the Pythagorean theorem(a^2 + b^2 = c^2) to find out if 3 sides will form a right angle.

Hope this helps!! :D

Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

First, you have to find the total number of socks. The total is 14. Now, since you choose 2 socks out of 14 in total, the probability is 2/14 or about 14%. To find the percent, just divide the numerator by the denominator. The answer you get is in decimal form. Multiply the decimal by 100. Then, there is your percent.
