Question

A lamppost casts a shadow 44 feet long. The angle measure of the shadow is 33°

Answer 1

@knock im sorry last one hehe can you help ?

Answer 2

Yes, it should be x=44*tg(33)

Answer 3

is the tg tangent?

Answer 4

Yes, x=28.5739...

Answer 5

Two birds sit at the top of two different trees 57.4 feet away from one another. The distance between the second bird and a bird watcher on the ground is 49.6 feet.

Answer 6

would you use cosine for this?

Answer 7

@knock

Answer 8

I'd use tangent again, and it's inverse, arctangent to find the value of x, as

tg(x)=49.6/57.4; x=arctg(49.6/57.4)=40.8306...

Answer 9

your right :(..... ok i have another problem

Answer 10

In △PQR, find the measure of ∡P.

Answer 11

ok this one would be sine, right?

Answer 12

Yep, you've got it!

Answer 13

yay! how do i put it into the calculator?

Answer 14

@knock

Answer 15

Ok, what's the definition for sin(x)?

Answer 16

oppsite over hypotenusse

Answer 17

is it 30.4?

Answer 18

@knock

Answer 19

How do you get it?

Answer 20

idk i just put the two numbers in the claculator... :(

Answer 21

@knock

Answer 22

Ok, but 33.8/57.6=0.5868

Answer 23

:(

Answer 24

so sin(x)=0.5868, x=arcsin(0.5868)=35.93... degrees

Answer 25

Do you understand?

Answer 26

yes ty
