Question

I need help with my MATLAB code. I having problems with the double values of trig. For the following code, I should get both t1 and t_1 to be equal to 160 degrees, but I don't. t1 = 160 and t_1 = 20. I know that asind(b/sind(theta2)) could equal to both 160 degrees and 20 degrees. So, how do I create a program that will give me a value that t1 and t_1 will equal to. To be clear I would want a set of code that outputs 160 degrees in this case because t1 = 160 and t_1 = 20, 160. I want the output to be a value that t1 = t_1.

clc;
clear all;

theta1 = 160;
theta2 = 35;

a = cosd(theta1)*sind(theta2)
b = sind(theta1)*sind(theta2)

t1 = acosd(a/sind(theta2))
t_1 = asind(b/sind(theta2))
