Answer:

A) \frac{15}{8}

Step-by-step explanation:

remember Soh Cah Toa!!

sin=\frac{opposite}{hypotenuse}\\ cos=\frac{adjacent}{hypotenuse} \\tan=\frac{opposite}{adjacent} \\\\cos=\frac{8}{17}\\\\a^2+b^2=c^2\\8^2+b^2=17^2\\64+b^2=289\\b^2=225\\\sqrt{b^2} =\sqrt{225}\\b=15=opposite\\\\tan=\frac{15}{8}

Flauer [41]

Answer:

7/8 of a gallon

Step-by-step explanation:

First find a common denominator for each of the values, in this case eighths. Next, add the total water used for the tomatoes and peppers (you'll get 7/8 gallons). Then, convert the 2 and a half gallons to eighths, getting 20/8 of a gallon. Next, subtract the 7/8 from the 20/8; getting 13/8. Since you need to find the amount of water used for the lettuce, subtract the last value from 3/4 gallons (or 6/8)

An observer in a hot air balloon sights a building that is 50 m from the balloon's launch point. The balloon has risen 165 m. Wh
Kaylis [27]
Notice the picture,
recall your SOH, CAH, TOA
\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}

you have,
opposite side, 165
adjacent side, 50
and the angle

that means, we'll need Mrs. tangent
thus 
\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(\theta)=\cfrac{165}{50}
\\ \quad \\
 tan^{-1}\left[ tan(\theta) \right]=tan^{-1}\left[ \cfrac{165}{50} \right]
\\ \quad \\
\theta=tan^{-1}\left[ \cfrac{165}{50}\right]
\\ \uparrow  \\
 \textit{angle of elevation}\iff\textit{angle of depression}

docker41 [41]

Given :

Mr. Turner employer pays 100% of his medical insurance. He has rent of $800 and $600 for car payment, $100 light bill, and $300 car insurance. His payroll and income taxes are estimated to be $287.

To Find :

What is his necessary monthly salary to have a gross income to meet his total expenses including the payroll and income taxes.

Solution :

Minimum salary to bear all expenses is :

S = Basic expenses + Payroll and taxes

S = $( 800 + 600 + 100 + 300 + 287)

S = $2087.00

Therefore, monthly salary is $2087.00 .

Hence, this is the required solution.
