Answer:
x=27 and NL = 40
Step-by-step explanation:
by properties of secants starting from common point-
LK x LJ = LM x LN
10 * (10+42) = 13 * (13+X)
X = 27

Answer:
a=0.2
Step-by-step explanation:
Let's solve your equation step-by-step.
2.8=14a
Step 1: Flip the equation.
14a=2.8
Step 2: Divide both sides by 14.
14a/
14
=
2.8/
14
a=0.2
Answer:
a=0.2
