Answer 1

@mathmale Sorry my computer froze

Answer 2

the length of the base = CB = 2 x BD
so all we need to do is find BD

\[\tan ( 52) = \frac{ opposite \ side }{ adjacent \ side \ } = \frac{ AB }{ BD }\]\[BD = \frac{ AB }{ \tan 52 } = \frac{ 91 }{1.27 } =71.65 \]

now multiply this value by 2 and that is the length of the base..

got it :) ?

Answer 3

142?

Answer 5

BP = OT

Answer 6

For the known angle of 33 degrees, the 7000-ft side is the opposite side, and x is the adjacent side.
Which trig function relates the opposite to the adjacent sides?

Answer 7

This is a reminder: SOH CAH TOA

SOH: sine=opposite/hypotenuse
CAH: cosine=adjacent/hypotenuse
TOA: tangent=opposite/adjacent

Answer 8

SOH?

Answer 9

SOH means the sine is the opposite over the hypotenuse
I asked which trig function relates the _opposite_ to the _adjacent_?

Answer 10

Tangent

Answer 11

Right.

That means you write:

\(\tan 33^o = \dfrac{opp}{adj} \)

\(\tan 33^o = \dfrac{7000}{x}\)

Now you solve for x.

\(\dfrac{\tan 33^o}{1} = \dfrac{7000}{x}\)

Cross multiply:

\(x \tan 33^o = 7000 \times 1\)

Divide both sides by tan 33:

\(x = \dfrac{7000}{\tan 33^o}\)

Now use a calculator to find x.
