suppose you are headed toward a plateau 58 meters high if the angle of elevation to the top of the plateau is 20° how far are yo

vaieri [72.5K]

Answer:

159.35 meters

Step-by-step explanation:

-We use the law of Sines to calculate the distance to the plateau's base.

-The angle of depression (90-20=70°) corresponds to this distance:

$\frac{a}{Sin \ A}=\frac{b}{Sin \ B}\\\\\frac{58}{Sin \ 20\textdegree}=\frac{x}{Sin \ 70 \textdegre}\\\\x=Sin \ 70\textdegree\times 58/Sin \ 20\textdegree\\\\=159.35\ m$

Hence, the distance to the base is 159.35 meters

168 students play at least one sport 35% of students at the school how many students are at the school

mash [69]

X= number of students in school

Total number of students multiplied by % equals portion of students

x * 35%= 168
0.35x= 168
divide both sides by 0.35
x= 480

ANSWER: There are 480 students in the school.

Hope this helps! :)
