Step-by-step explanation:
In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0
Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]
I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown
A = (1.91, 0)
B = (4.37, 0)
So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians

Answer:
Width of the pool = 15 yards
Step-by-step explanation:
Given that:
Length of diagonal of swimming pool = 29 yards
Length of the pool = 25 yards
Let,
w be the width.
This will form a right angled triangle where the diagonal will be hypotenuse.
Using Pythagorean theorem;
![(25)^2+(w)^2 = (29)^2\\625+w^2=841\\w^2= 841 - 625\\w^2 = 216](https://tex.z-dn.net/?f=%2825%29%5E2%2B%28w%29%5E2%20%3D%20%2829%29%5E2%5C%5C625%2Bw%5E2%3D841%5C%5Cw%5E2%3D%20841%20-%20625%5C%5Cw%5E2%20%3D%20216)
Taking square root on both sides
![\sqrt{w^2}=\sqrt{216}\\w=14.70](https://tex.z-dn.net/?f=%5Csqrt%7Bw%5E2%7D%3D%5Csqrt%7B216%7D%5C%5Cw%3D14.70)
Rounding off to nearest whole number
w = 15 yards
Hence,
Width of the pool = 15 yards
