Angle W:

180 = 90 + 57 + W

180 = 147 + W

W = 33 degrees

Using trigonometry functions to find the side lengths. (SOH CAH TOA)

Side XZ:

cos(57) = XZ / 18

XZ = cos(57) x 18

XZ = 9.8 units

Side XW:

sin(57) = XW / 18

XW = sin(57) x 18

XW = 15.1 units

Hope this helps!! :)

A group of 48 senior citizens attended a baseball game. The number of women in attendance was 12 more than the number of men. Ho
Sergio [31]

Answer:

18 men attended the baseball game, and 30 women attended the baseball game.

Step-by-step explanation:

Let the number of men in attendance be x and the number of women in attendance be x+12.

No. of men + <em>No. of women</em> = <u>48 </u>

x +<em> x + 12</em> = <u>48</u>

2x + 12 = 48

2x = 48 - 12

    = 36

x = 36 ÷ 2

x = 18

x+12: 18 + 12 = 30
