Answer:
Length of the side opposite to angle
is 31.49
Step-by-step explanation:
Included angle can be defined as the angle in between two sides of the triangle.
So angle
is in between sides 16 and 21.
Refer to the attachment for triangle diagram.
To find the length of opposite side, use cosine rule as follows

From the diagram, 
Substituting the values in the formula,

Simplifying,


Taking square root on both sides,


Therefore length of third side is 31.49
The price of a flower bouquet is $2.75 according to the information on the question above. This problem can be solved using two linear equations with two different variables based on the transaction. The first equation is 3x +5y= 25.75 and the second equation is 8x+2y=29 which can be simplified as y=14.5-4x. You can find the x by substituting the "y" variable on the first with the second equation resulting in "x =2.75" which is the price of the flower bouquet<span>.</span>

Answer:
-2[h(3)] = 0
Step-by-step explanation:
Step 1: Define
h(x) = 2x - 6
Step 2: Find h(3)
h(3) = 2(3) - 6
h(3) = 6 - 6
h(3) = 0
Step 3: Find -2[h(3)]
-2(0)
0
