A parcel of land is in the shape of a rectangle with length L(in feet). sixty-five percent of the length is waterfront and 70 fe

OlgaM077 [116]

The length of the land = the length of the waterfront + the length of dry land

The length of the land = L
The length of the waterfront = 0.65L
The length of the dry land = 70 feet

L = 0.65L + 70
L - 0.65L = 70
0.35L = 70
L = 70 ÷ 0.35
L = 200 feet

HELP PLEASE<3 <br> Find the missing angle <br> Btw its trigonometry

ira [324]

Answer:

x = 16.6

Step-by-step explanation:

Since we know the measure of an acute angle (31 degrees) of a right angle triangle, and of the side opposite to the angle (10), and we need to find the measure of the adjacent side "x", we use the tangent function:

$tan(\theta) = \frac{opposite}{adjacent} \\tan(31^o)=\frac{10}{x}\\x=\frac{10}{tan(31^o)} \\x \approx 16.64279$

which rounded to one decimal is

x = 16.6
