Can someone please help me do this

Viefleur [7K]

Answer:

Step-by-step explanation:

CD is Pole

∠CAD = 4° {Alternate interior angles}

ΔCAD,

$\dfrac{opposite \ side}{adjacent \ side}= tan 4\\\\ \dfrac{90}{AD}=tan \ 4\\\\ \dfrac{90}{AD} = 0.069\\\\90 = 0.069*AD\\\\ \dfrac{90}{0.069}=AD\\\\AD = 1304 \ ft$

In ΔCDB,

∠B = 5° {Alternate interior angles}

$Tan \ 5 = \dfrac{90}{BD}\\\\0.09* BD = 90\\\\BD = \dfrac{90}{0.09}\\\\BD = 1000 \ ft$

In a sample of students, 125 said they exercise on a regular basis. How large was the sample if 27.3% said they exercised on a r

krek1111 [17]

First, let's declare a variable

x = # of students

Now, let's create an equation to model the problem.

x * 0.273 = 125

Divide both sides by 0.273

x = 457.8 = 458 students.

Note, I rounded to the nearest whole number.
