Is this MATLAB code correct?

I'm trying to run it, but it won't finish, and I'm getting no errors.

I'm trying to solve this system of 2 equations for the two unknowns, theta3 and theta4.

eq 1: R2*cos(theta2) + R3*cos(theta3) + R4*cos(theta4) - R1*cos(theta1) = 0

eq2 : R2*sin(theta2) + R3*sin(theta3) + R4*sin(theta4) + R1*sin(theta1); = 0

clear all
clc

R1 = 2.4;
R2 = 0.8;
R3 = 1.23;
R4 = 1.55;

theta2 = 49 * (pi/180); %(radians)
theta1 = 0;

syms theta1 theta2 theta3 theta4 R1 R2 R3 R4
assume(0 <= theta3 | theta3 <= 2*pi | 0 <= theta4 | theta4 <= 2*pi)
[theta3, theta4] = solve([0 == R2*cos(theta2) + R3*cos(theta3) + R4*cos(theta4) - R1*cos(theta1),...
0 == R2*sin(theta2) + R3*sin(theta3) + R4*sin(theta4) + R1*sin(theta1)], [theta3,theta4]);
solutions = [theta3, theta4]

Explanation / Answer

0 == R2*sin(theta2) + R3*sin(theta3) + R4*sin(theta4) + R1*sin(theta1)], [theta3,theta4]);

There is an extra " ] " in the above line which is causing problems for you.
