Answer:
x = 30
Explanation:
Let the measure of ∠MKQ be x°.
It's given that:-
-  Measure of ∠JKL is twice the measure of ∠MKQ.
 
⇒ ∠JKL = 2∠MKQ 
⇒ ∠JKL = 2x° _____ (eqn.1)
- ∠JKL & ∠MKQ are complementary angles.
 
⇒ ∠JKL + ∠MKQ = 90° 
⇒ 2x° + x° = 90°
⇒ 3x° = 90°
⇒ x° = 

∴ Hence ,
- ∠MKQ = 30°
 - ∠JKL = 2∠MKQ = 2×30 = 60°
