How to find the value at a certain angle of the sinusoid?

Good night sir, I have two sinusoidal functions whose sinusoidal maximum value is = 20 and the sinusoidal minimum = -20, we know that the maximum point the angle of the sinusoid = 90 ° or π / 2 in radians and corresponds to the value 20 I need to know an equation in which the second (red) signal switches will be valid, I know the angle is 150 ° and the corresponding value will be 10.30 (given by the software) but I want to know an equation for me to reach that value
All I need to know, to be clearer is an equation where I will find the value in the blue sine when the red signal switches, I know that the angle at which it switches is 150 ° or 5π / 6 in radians. What is the equation for me to reach the value 10.30 that the red signal switches.

Thanks to anyone who can help.
