Answer:

m∠C=65°

Step-by-step explanation:

m∠B=90°

m∠A=25°

m∠A+m∠B+m∠C=180°

25°+90°+m∠C=180°

m∠C=180°-(90°+25°)

m∠C=65°

Hope it helps! :)

Answer:

65 degrees

Step-by-step explanation:

All angles of a triangle have to add up to 180 degrees. After establishing that, we can see that there are two angles given. 25 degrees and a 90-degree symbol. So if two angles add up to 115 degrees, we can do 180-115=65 to find the angle of C.

A soccer team roster has 14 players on it. How many groups of 11 players can be created ?

Answer:

364 groups of 11 players can be created

Step-by-step explanation:

The order in which the players are selected is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Teams of 11 players from sets of 14. So

$C_{14,11} = \frac{14!}{11!(14-11)!} = 364$

364 groups of 11 players can be created

Given:

$PQRS\sim TUVW$

In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15

To find:

The scale factor from PQRS to TUVW.

Solution:

We have,

$PQRS\sim TUVW$

We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.

The scale factor is:

$k=\dfrac{VW}{RS}$
