Answer:
about 4,242,424 in the year of 1999
Step-by-step explanation:
In this item, we have:
A = 6x² + x +3
h = 3x
where ''A'' is area and ''h'' is height. From the statement above,
length of base, b = A / h
<em> b = (6x² + x + 3)/3x
</em>
Thus, the expression for the length of the base is 6x²+x+3 / 3x.
Answer:
h = 9.9
Step-by-step explanation:
Since the triangle is right we can use the tangent ratio to find h
tan51° =
= ![\frac{h}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B8%7D)
Multiply both sides by 8
8 × tan51° = h
⇒ h = 9.9 cm ( to 1 dec. place )
