Segments BA and CA are drawn perpendicular to two chords. The segments are congruent, so that makes the two chords congruent (they are the same distance from the center of the circle). So segments GF and HE are congruent.

In the second problem, it helps to ignore the pieces of information you don't need. Angle GET is formed by two secants, IE and NE. I've attached a diagram that shows the angle you're trying to find and its TWO intercepted arcs. A fact about circles is that if the angle is formed by two secants (their intersection is outside the circle), the measure of the angle is half the DIFFERENCE of the measures of the intercepted arcs.

The measure of angle GET = 1/2 (74 - 18) = 1/2(56) = 28 degrees.

How do you find the height of a triangle without knowing the area

g100num [7]

Well you already know your side lengths, so you use this formula S=1/2(A+B+C). For A put in one of your side lengths, for B put one of your side lengths, and for C put one of your side lengths. After you do that solve. But your not done. Once you find out what S equals by doing the formula I just showed you, you have to do another formula which is A= S(S-A)(S-B)(S-C). Once again plug in your side lengths for A,B, and C but then plug in your S value. (Remember you already found your S value by doing the first formula I showed you). Then do the math and then you will find your answer.

A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver

laila [671]

1. What’s the probablity of a second person winning the small prize?
There are now 99 total marbles, and 24 silver marbles. So, 24/99 is 0.24 probability.
2. Which player is most likely to win a big prize?
Since each player draws a silver marble (aka a small prize) there are less small prize marbles in the bag after each turn. So, the first person would have a 5% chance (or 0.05)of winning the big prize gold marble, but the last person would have a slightly bigger chance (5.15% or 0.0515) of winning a big prize.
3. How could the game be made fair for each player?
Well it’s quite simple, just have each player return their marble and the number of marbles would be kept constant, giving everyone an equal chance. Or you could have them all play at the same time, either way.
4. Same answer as 3

Brittany graphs the point (6,3) on a coordinate grid. Which describes where she

Daniel [21]

Answer:

D. 6 units to the right and 3 units up

Step-by-step explanation:

Given

Point (6,3)

Required

Position of the point.

The general format if a coordinated grid is (x,y)

Where x and y represent the x and y axis respectively

The following conditions are to be considered when positioning a point on a coordinate grid.

1. If x is positive, then it points to the right;

2. If x is negative, then it points to the left

3. If y is positive, then it points upwards

4. If y is negative, then it points downwards

Having said this;

By comparison

x = 6 and y = 3

x and y are both positive.

Condition 1 and 3 above are satisfied.

Hence, the grid coordinates is 6 units to the right and 3 units upwards.

Option D is correct and others are incorrect
