Question

HELP!!! I AM SOO CONFUSED!!

I need help writing the sine, cosine, and tangent ratios for 11 years ago

Answer 1

\[\sin A=\frac{\text{opposite side}}{\text{hypotenuse}}\]\[\cos A=\frac{\text{adjacent side}}{\text{hypotenuse}}\]\[\tan A=\frac{\text{opposite side}}{\text{adjacent side}}\]

Answer 2

Sin A = 3 / 8.5

cos A = 8 / 8.5

tan A = 3 / 8

Answer 3

\[\checkmark\\\checkmark\\\checkmark\]

Answer 4

sin A = 0.35294118

cos A = 0.94117647

tan A = 0.375

Answer 5

i would leave them in fraction form, but simplify a little

\[3/8.5 = 6/17\\
8/8.5=16/17\\3/8=3/8\]

Answer 6

Okay, can you help me with two more problem?

Answer 7

probably

Answer 8

Okay, so why would a measurement not be consistent if the we use the Converse of the Pythagorean Theorem?

Answer 9

i thought it was a right angled triangle,

Answer 10

The drawling below is what I am using. Under the ramp do you see a triangle?
This will help you understand what I am talking about.

Answer 11

well according to that diagram (assuming the ground is flat), it should be right angled

Answer 12

if we use pythag.

hypo = sqrt(adj^2+opp^2)

but this doesn't quite give 8.50

Answer 13

Right, so my teacher said to make the sides as best as you can. (How long they would be in real life.)
So, I marked adjacent side 8 ft and the opposite side 3 ft. but when you do the Pythagorean theorem the hypothenuse is 8.5

Answer 14

with pythag, i get 8.544

Answer 15

maybe we should have used the Law of cosines instead

Answer 16

And that doesnt go with the Converse of the Pythagorean Theorem so I was wondering why the measurement are not consisent..

Answer 17

The question only asked for me to do The Pythagorean Theorem and Converse of the Pythagorean Theorem.
