Answer:

x = 8.66
y = 17.321

Step-by-step explanation:

Calculated based on 2 given angles and 1 given side.

∠C = 180° - A - B = 1.0472 rad = π/3 = 60°

a = c·sin(A)/sin(C) = 8.66025 = 5\sqrt{3}

b = c·sin(B)/sin(C) = 17.32051 = 10\sqrt{3}

Area = \frac{ab·sin(C)}{2} = 64.95191

Perimeter p = a + b + c = 40.98076

Semiperimeter s = \frac{a + b +c}{2} = 20.49038

Height ha = \frac{2×Area}{a} = 15

Height hb = \frac{2×Area}{b} = 7.5

Height hc = \frac{2×Area}{c} = 8.66025

Median ma = \sqrt{(a/2)^{2}  + c2 - ac·cos(B)} = 15.61249

Median mb = \sqrt{(b/2)^{2}  + a2 - ab·cos(C)} = 8.66025

Median mc = \sqrt{(c/2)^{2}  + b2 - bc·cos(A)} = 11.45644

Inradius r = \frac{Area}{s} = 3.16987

Circumradius R = \frac{a}{2sin(A)} = 8.66025

Need to know this now pls !!! NEED THE PROCESS , TOO!!!<br><br> x squared - 18x = -117
nydimaria [60]

Answer:

x = 9 + 6i or x = 9 - 6i

Step-by-step explanation:

x² - 18x + 117 = 0

Complete the square and solve:

(x - 9)² - 81 + 117 = 0

(x - 9)² + 36 = 0

(x - 9)² = -36

x - 9 = ±sqrt(-36)

x - 9 = ±sqrt(-1).sqrt(36)

i = imaginary number = sqrt(-1)

x - 9 = ±6i

x = 9 ± 6i

There are no real solutions, only imaginary ones

9 + 6i and 9 - 6i

An NFL coach sometimes uses a defense that utilizes 3 defensive linemen, 4 linebackers, and 4 defensive backs. His roster (the p
Alexandra [31]

Answer:

68,600

Step-by-step explanation:

The order of the players is not important. For example, a defensive line of Shaq Lawson, Ed Oliver and Jerry Hughes is the same as a defensive line of Ed Oliver, Shaq Lawson and Jerry Hughes. 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)!}

Defensive Lineman:

3 from a set of 8. So

C_{8,3} = \frac{8!}{3!5!} = 56

56 combinations of defensive lineman

Linebackers:

4 from a set of 7. So

C_{7,4} = \frac{7!}{4!3!} = 35

35 combinations of linebackers

Defensive backs:

4 from a set of 7. So

C_{7,4} = \frac{7!}{4!3!} = 35

35 combinations of defensive backs

How many different ways can the coach pick the 11 players to implement this particular defense?

56*35*35 = 68,600

68,600 different ways can the coach pick the 11 players to implement this particular defense
