Answer:
BC = 10.24
Step-by-step explanation:
You can use the Pythagoras theorem for this question
+
= 
a = 8cm
b = ???
c = 13cm
We will solve for B (length BC)
+
= 
+
= 
Rearrange for b
=
-
= 105
b = 
b = 10.24
Answer:
D
Step-by-step explanation:
The slope = 4/2 = 2
and one point on the graph ( point B) is (5, 6) so point-slope equation is
y - 6 = 2(x - 5)
