Going off the given statement we have an angle and a side in each triangle that are congruent to each other. Since vertical angles are congruent, we have now 2 angles and a side, or more specifically, an angle then a side then an angle, which makes those triangles congruent by ASA. That's #3. If the triangles are already proven to be congruent, then anything else that's congrunet between the triangles is because CPCTC. That's #4.

3. PRQ=SRT ASA theorem- angle side angle.

4. PR=SR by the CPCTC Theorem- concurrent parts of congruent triangles are congruent.

  • 9

======================================

Explanation:

7+6 = 13. Divide this over 5 to get 13/5 = 2 remainder 3. The quotient 2 is something we don't care about. <u>We only worry about the remainder</u>. Therefore 7+6 = 3 (mod 5)

-------------

2+1 = 3 (mod 5) for similar reasoning as above. 3/5 = 0 remainder 3.

-------------

20 = 9 (mod 11) since 20/11 = 1 remainder 9. Imagine you had 20 cookies and 11 friends. Each friend would get 1 whole cookie (quotient) and there could be 9 left over (remainder).

-------------

35/11 = 3 remainder 2

Or you could use repeated subtraction like so to find the remainder

35-11 = 24

24-11 = 13

13-11 = 2

The last result (2) is smaller than 11, so we stop here and this is the remainder.

Therefore, 35 = 2 (mod 11)

--------------

Here's another way to think of it. Consider you have $35 in your pocket. Let's say a store is selling trinkets for $11 each. We can pose these key questions:

  • What is the most number of trinkets you can buy?
  • If you buy that max amount, how much will you have left over?

The answer to the first question is 3 trinkets because 3*11 = 33 dollars is under the budget of $35. The amount left over is 35-33 = 2 dollars which is the remainder. It's not larger than 11, so we cannot buy any more trinkets at this point.

PLEASE HELP ITS A TIMED TEST!!!
nexus9112 [7]

Answer:

First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.

To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.

240 = 25x + 40

subtract 40 from each side

200= 25x

divide by 25

8 = x

8 months

10 + 7r = 45

7r = 35

r = 5

Find the area of the shaded region. Round your answer to the nearest tenth if needed.<br><br> 2B
SCORPION-xisa [38]

Answer:

The area of the park is calculated through the equation,

A = 0.5ab(cos C)

Substituting the given above,

A = 0.5(533 ft)(525 ft)(cos 53°)

A = 84201.44 ft²

2. We find the radius of the second figure by the equation,

r = C / 2π

Substituting,

r = (30 in) / (2π) = 4.77 in

The radius of the first one is 9 inches. Getting the difference of these two figures will give us an answer of 4.225 inches.

Diameter of the basketball rim = 18 inches

Circumference of the basketball = 30 inches

You would have to fin the area so= pi*r^2

Basketball rim = 3.14 * (18/2)^2 = 3.14 * 9^2 = 3.14 * 81 = 254.34 in^2

The find the Circumference so= 2*pi*r

30 = 2*3.14*r

r = 30 / (2*3.14) = 30 / 6.28 = 4.78 inches

basketball = 3.14 * (4.78)^2 = 3.14 * 22.85 = 71.75 in^2

254.34 - 71.75 = 182.59 in^
