Answer:

491400

Step-by-step explanation:

Given : A club has 28 members.

To Find : . How many ways are there to choose four members of the club to serve on an executive committee?

Solution:

We are supposed to choose  four members of the club out of 28.

So, we will use combination

Formula : ^nC_r=\frac{n!}{r!(n-r)!}

n = 28

r = 4

Substitute the values :

^{28}C_{4}=\frac{28!}{4!(28-4)!}

^{28}C_{4}=\frac{28 \times 27 \times 26 \times 25 \times 24!}{4!(24)!}

^{28}C_{4}=\frac{28 \times 27 \times 26 \times 25 \times 24}{4 \times 3 \times 2 \times 1}

^{28}C_{4}=491400

Hence there are 491400 ways o choose four members of the club to serve on an executive committee

Wing figures, solve for x. Complete parts (a) 80° 53​
Korolek [52]

Answer:

x = 25°

Step-by-step explanation:

Applying,

Sum of the angle in the triangle = 180°

From the diagram,

First angle of the triangle = 55° (vertically opposite angles are equal)

Second angle of the traingle = 180-80 = 100° (sum of the angle in a straight line)

Third angle of the triangle = x

Therefore,

x+55+100 = 180

x+155 = 180

x = 180-155

x = 25°
