A cell phone tower is anchored by two cables on each side for support. The cables stretch from the top of the tower to the ground, with each being equidistant from the base of the tower. The angle of depression from the top of the tower to the point in which the cable reaches the ground is 23°. If the tower is 140 feet tall, find the ground distance between the cables.

Kyle has created a video game called Falling Stars in which the player zaps stars from the sky. A certain number of stars must be zapped before the player can move on to the next level. Each zapped star is worth the same number of points on each level. The table shows how many stars will need to be zapped and the points that can be earned at each level. Without extending the table, Kyle wants to know how many stars will need to be zapped in Level 30. Which expression can be used to help Kyle find the answer? How many stars will need to be zapped in Level 30?A) 5(30) + 40; 190 stars B) 5(40) + 25; 225 stars C) (30 + 5) + 40; 75 stars D) 5(30 - 5) + 40; 165 stars
