Answer:
C
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 19 and h = 16 , thus
A = 0.5 × 19 × 16 = 152 yd² → C
38 14+8+16 To get perimeter add all sides
Answer:
Yes
Step-by-step explanation:
Substituting in x = -7, we get y = 6(-7) = -42, which is the same as the y coordinate of the given point.
Answer: 
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>
