Answer:

7π/18 radians

Step-by-step explanation:

A reference angle for angle β is the positive acute angle made by the terminal side of angle β and the x-axis.

A semi-circle angle has a measure of π radians.

The angle of the figure (in absolute value) can be decomposed as the addition of its reference angle and π radians. Therefore:

π + reference angle = 25π/18

reference angle = 25π/18 - π

reference angle = 7π/18 radians

The area of a rectangular horse pasture is 268,500 square yards. The length of the pasture is 5 yards less than three times the

Setler79 [48]

Answer: width = 300

<u>Step-by-step explanation:</u>

Area (A) = Length (L) x width (w)

Given: A = 268,500

L = 3w - 5

w = w

268,500 = (3w - 5) x (w)

268,500 = 3w² - 5w

0 = 3w² - 5w - 268,500

0 = (3w + 895) (w - 300)

0 = 3w + 895 0 = w - 300

-985/3 = w 300 = w

Since width cannot be negative, disregard w = -985/3

So the only valid answer is: w = 300
