Step-by-step explanation:
<u>The goal of the question</u>
Find the value of 2abcosC
<u>Given information</u>
a = 4
b = 3
c = 2
<u>Given formula (Law of Cosine)</u>

<u>Substitute values into the formula (Leave 2abcosC as it is)</u>

<u>Simplify the exponents</u>

<u>Simplify by addition</u>

<u>Add 2abcosC on both sides</u>


<u>Subtract 4 on both sides</u>

Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar we can find x using similarity ratio
14/8 = (x+6)/(x-3) simplify first expression
7/4 = (x+6)/(x-3) cross multiply expressions
7×(x-3) = 4×(x+6)
7x-21 = 4x + 24 add like terms
3x = 45
x = 15
