<h3>
Answer: Approximately 23.0 cm</h3>
=====================================================
Work Shown:
a = 20.3
b = unknown
c = 30.7
Apply the pythagorean theorem to find b
a^2 + b^2 = c^2
(20.3)^2 + b^2 = (30.7)^2
412.09 + b^2 = 942.49
b^2 = 942.49-412.09
b^2 = 530.4
b = sqrt(530.4)
b = 23.0304146727757 value is approximate
b = 23.0
I rounded to one decimal place because the other values (20.3 and 30.7) were to one decimal place.
Answer:
6g -3g +6g -3g = 5+6-11-3+5-11
6g=-18
6g= -18 /÷6
g= -3
