Question

find the measure of ∠ykt.

Explanation:

Step1: Set up the equation

Since \( \angle DKY = 90^{\circ}\), we have \(51+(h + 45)=90\).

Step2: Solve for \(h\)

$$
LATEXBLOCK0
$$

Step3: Find \( \angle YKT\)

Substitute \(h=-6\) into \(h + 45\). So \( \angle YKT=(-6)+45 = 39^{\circ}\)

Answer:

\(39^{\circ}\)
