Triangle P Q R is shown. The length of P Q is 17, the length of Q R is 15, and the length of P R is 14. Law of cosines: a2 = b2

Maksim231197 [3]

Answer:

P = 57°

Step-by-step explanation:

Given the following :

PQ = 17

QR = 15

PR = 14

Using the cosine formula since the length of the three sides are given:

a2 = b2 + c2 – 2bccos(A)

To find P:

QR^2 = PQ^2 + PR^2 – 2(PQ)(PR)cos(P)

15^2 = 17^2 + 14^2 – 2(17)(14)cos(P)

225 = 289 + 196 - 476 cosP

476*CosP = 485 - 225

476*CosP = 260

CosP = 260/476

CosP = 0.5462184

P = Cos^-1(0.5462184)

P = 56.892029

P = 57°

5. During the season, the Rangers played 25 games. They won 14 of the games.

sertanlavr [38]

Answer is 11/25 games lost which is 44%.

Step by step. 25 games minus 14 they won equals 11 games lost out of 25.

11 out of 25 = 11/25.

11/25 as a % - 11 divided by 25 = .44 which is 44%.

Check your work, 44% of 25 games = 11 games lost.
Problem solved.

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.

il63 [147K]

y = mx + c

7 = 4(-8) + c

c = 39

The equation is y = 4x + 39

y - 7 = 4 ( x - (-8))

y -7 = 4 (x +8)
