Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.

m(∠GFE) = \frac{1}{2}\text{m (arc} FE)

83° = \frac{1}{2}\text{m (arc} FE)

m(arc FE) = 166°

Describe what solving a trigonometric equation is.
AleksAgata [21]
That's an awfully broad question.  Could you not be more specific?

A basic example:  Suppose you are told that sin theta = 1/2.  Solving this equation would require finding the measure of the angle theta.  In this case the answer would be "30 degrees," or "pi/6 radians."

PLEASE HELP! 100 POINTS!

Answer:

Mrs. Etercsid

Step-by-step explanation:

One thing we can do is just multiply the averages by the percents in each class and compare from there.

To get from percentages to decimals, we can divide by 100.

For Mr. Tats:

Homework: 25 % -> 0.25

Participation: 10% -> 0.1

Test: 40% -> 0.4

Final: 0.25 -> 0.25

For Mrs. Etercsid:

Homework: 15% -> 0.15

Participation: 10% -> 0.1

Test: 60% -> 0.6

Final: 15% -> 0.15

We can then multiply the averages by the decimals for each teacher and add them up.

Mr. Tats:

0.25 * 81 + 0.1 * 57 + 0.4 * 93 + 0.25 * 87 = 84.9

Mrs. Etercsid:

0.15 * 81 + 0.1 * 57 + 0.6 * 93 + 0.15 * 87 = 86.7

You would get the higher grade with Mrs. Etercsid
