Question

Have a Geometry: Basic Trig Question, Not seeking to get answers from you, rather a step by step guide

Answer 1

Find the length of the base of the following pyramid, given the height of the pyramid is 211 meters and the angle of elevation of the base of the pyramid is 62°. Round to the nearest whole number.

Answer 2

How do i set this up

Answer 3

So it is 90 pyramid right?

Answer 4

*90 degree

Answer 5

Hi again lol, um yes it is a 90 degree pyramid

Answer 6

So we have

Answer 7

whoa, that was quick, yes that is the one

Answer 8

Well we are not working with the hypotenuse, so which trig function features opposite and adjacent?

Answer 9

we are working with the tangent function right?

Answer 10

yes, we are

Answer 11

sorry glitchy

Answer 12

so \[\tan 52 Degrees = 211/a\]

Answer 13

and whatever the adjacent is, the base of the pyramid is double

Answer 14

Well, close \[\large \sf Tan62=\frac{211}{Base}\] So do the trick and change the a and c

Answer 15

oh, im sorry about that

Answer 16

Base= 211/tan 62

Answer 17

Correct. So now we just crunch the numbers

Answer 18

i wrote it down in correct format, typing on phone is a bit weird

Answer 19

alrighty, so how would i "crunch the numbers"

Answer 20

Well, I meant calculate it. You know do \(\huge \sf \frac{211}{tan62}\)

Answer 21

ahhh, ok

Answer 22

tan of 62 degrees is roughly 1.88, on phone calculator

Answer 23

Ye that looks good to me

Answer 24

so 211+1.88

Answer 25

not plus, divided

Answer 26

Yes 211/1.88

Answer 27

112.234

Answer 28

That would be your answer

Answer 29

so double that is 224, the answer is c

Answer 30

Why are we doubling it again?

Answer 31

seriously, thankyou for helping me with these, it means alot to me, im not corrently in the best place, graduation status and this really helps

Answer 32

the triangles 90 degree angle is in the center of the pyramid, finding the tan gives me half of the whole base of the pyramid

Answer 33

Ahh, I see. That looks right, then

Answer 34

And no problem, I'm happy to help.

Answer 35

Should i keep question open or close it?

Answer 36

You have had your question resolved, so it would be time to close it.
