3. A golfer hits an errant tee shot that lands in the rough. A marker in the center of the fairway is 150

yards from the center of the green. Whilestanding on the marker facing the green, the golfer turns
110 toward his ball. He then paces off 35 yards to hit his ball. See figure. How far is the ball from the
center of the green? Round to the nearest yard

We can use the Pythagorean theorem to solve this problem. Let's call the distance from the ball to the center of the green "d". We know that the marker is 150 yards from the center of the green, and the golfer has paced off 35 yards in a direction 110 degrees from the marker.

Let's use x to represent the horizontal distance from the marker to the ball, and y to represent the vertical distance from the marker to the ball. Then, we have:

x = 35 * cos(110)

y = 35 * sin(110)

Using the Pythagorean theorem, we can find the distance "d" from the ball to the center of the green:

d^2 = x^2 + (y + 150)^2

Plugging in the values for x and y, we get:

d^2 = 35^2 * cos(110)^2 + (35 * sin(110) + 150)^2

d^2 = 1225 + (150 + 35 * sin(110))^2

Using a calculator, we can find that sin(110) = 0.939, so:

d^2 = 1225 + (150 + 31.65)^2

d^2 = 1225 + (181.65)^2

d^2 = 1225 + 32762.7225

Taking the square root of both sides:

d = sqrt(1225 + 32762.7225)

d = sqrt(33987.7225)

d = 183.83

Rounding to the nearest yard:

d = 184 yards

So, the ball is 184 yards from the center of the green.
