What is the equation to find the measure of an angle if it is represented as $$x + 15$$ ?

Set up the equation based on the context, e.g., $$x + 15 = 90$$ .

If angle A = $$2x$$ and angle B = $$3x$$ , what is the relationship between them?

Angle A and Angle B are supplementary if $$2x + 3x = 180$$ .

How do you find the measure of an angle represented as $$x - 20$$ ?

Set up an equation based on the context, e.g., $$x - 20 = 70$$ .

If angle C = $$4x$$ and angle D = $$x + 30$$ , how do you find x?

Set up the equation $$4x = x + 30$$ .

If angle E = $$x/2$$ and angle F = $$x + 10$$ , how do you find x?
