The measure of angle YQR= 21Degrees
How to solve for the measure of the angle
To solve the equation (16x - 27 = 5x + 6) for x, we'll first combine like terms and then isolate x:

Let's gather x terms on one side and constant terms on the other side:

\(11x = 33\)
Now, divide both sides by 11 to solve for \(x\):

x = 3
So, indeed x = 3 satisfies the equation.
Now, to find the value of ∡RQY:
Given x = 3, let's substitute x into the expression for ∡RQY:
∡RQY = 16x - 27
∡RQY = 16 * 3 - 27
∡RQY = 48 - 27
∡RQY = 21°
Therefore, the measure of angle ∡RQY is indeed 21° when \(x = 3\).
