In rectangle jklm, angle knl is 5x - 20. find the measure of angle jkl a) 90 b) none of the other answers are correct c) 80 d) 40 e) 60

we know that

if JKLM is a rectangle

then

the interior angles are equal to 90 degrees

so

∠MJK=∠JKL=∠KLM=∠LMJ=90°

therefore

the answer is

the measure of angle JKL is 90 degrees

.

step-by-step explanation:

goog may be able to you find that answer
