D = k + 20
j = 3k - 120
d = j
k + 20 = 3k - 120
20 + 120 = 3k - k
140 = 2k
140/2 = k
70 = k.....so Katie weighs 70 lbs
David and Johnathan each weigh 90 lbs
Hey there! :D
Vertical angles are congruent, they have the same measure.
So, <7 and <5 are vertical angles. They share the same vertex, and if you were to draw a straight line between them, it would connect and bisect them both equally.
<5= 45, so <7= 45.
I hope this helps!

5 • 2 = 10
5 • 3 = 15
5 • 4 = 20
5 • 5 = 25
5 • 6 = 30
5 • 7 = 35
5 • 8 = 40
5 • 9 = 45
5 • 10 = 50
5 • 11 = 55
5 • 12 = 60
