Answer:

To enable a set of three numbers to represent three sides of a triangle, sum of smaller two numbers must be greater than the largest number. Hence, only C can represent a triangle.

⚪ The sum of the measures of the interior angles of a triangle in Euclidean space is always 180 degrees

<em><u>The answer is none</u></em>

This is a 3 part question, PLEASE HELP ILL GIVE BRAINLY

Answer:

Angle of A = 90 degree-62 degree = 28 degree.

Step-by-step explanation:

tan (62) = opposite / adjacent = 10 / a ---> a = 10/tan (62) = 10/ 1.88 = 5.319

cos (62) = a/c --->c = a/cos (62) = 5.319 / 0.47 = 5.3 / 0.47 = 11.3

or another way.

sin (62) = 10 /c ---> c = 10/ sin (62) = 10 / 0.88 = 11.3

So Angle of A = 28 degree.

a = 5. 3

c = 11.3.

please give me brainliest. I hope it help.

47 decreased by nine times d what's the mathematical expression

Lilit [14]

Nine times d = 9*d = 9d

47 decreased by 9d = 47 - 9d

= 47 - 9d.

Seventeen candidates have filed for the upcoming county council election. 7 are women and 10 are men a) Is how many ways can 10

tankabanditka [31]

Answer: (a) 19448 ways

(b) 5292 ways

(c) 0.2721

Step-by-step explanation:

(a) 10 county council members be randomly elected out of the 17 candidates in the following ways:

= $^{n}C_{r}$

= $^{17}C_{10}$

= $\frac{17!}{10!7!}$

= 19448 ways

(b) 10 county council members be randomly elected from 17 candidates if 5 must be women and 5 must be men in the following ways:

we know that there are 7 women and 10 men in total, so

= $^{7}C_{5}$ × $^{10}C_{5}$

= $\frac{7!}{5!2!}$ × $\frac{10!}{5!5!}$

= 21 × 252

= 5292 ways

= $\frac{ ^{7}C_{5} * ^{10}C_{5}}{^{17}C_{10}}$

= $\frac{5292}{19448}$

= 0.2721
