In a sentence, describe the relevant angle relationship in the diagram. that is, descr

5x+3x=90+30
8x=120
(1/8) (8x) = (1/8) (120)
x=15

m<JAH= 3(15)=45
m<HAG= 5(15)=75

and the first one is 
<KAE and <EAF are adjacent angles whose measurements are equal to
<KAF; <KAF and <JAG are vertical angles and are of equal measurement.

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
