Please help, i will award medals. Question is below.

Answer 1

Answer 2

Ok
Sin45 = 7/x
x=7/(Sin45)

Tan45 = 7/y
y=7/Tan(45)

Answer 3

wouldnt you use hypotenuse =√2 * leg?

Answer 4

can you help me with that way? hypotenuse =√2 * leg?

Answer 5

bahrom?

Answer 6

Answer 7

@Mertsj

Answer 8

Yes, that equation, as well as the trigonometric solution, should both work out and give you the same result. Since the sum of the angles of a triangle is always 180, you know the missing angle is 45. So y=7 since it is opposite a 45 degree angle, it must be equal to the other side opposite the same angle. Now that you have the two legs, you know that in a 45-45-90 triangle the hypotenuse is rad2 times the leg (you can also use the Pythagorean Theorem. You'll get the same result)

Answer 9

That is an isosceles right triangle. In these cases, the legs are congruent, and the hypotenuse is the leg multiplied by the square root of 2.

Answer 10

So in this particular problem:
\[y=7 \]
\[x=7\sqrt{2}=7(1.414)=9.9\]

Answer 11

yes.

Answer 12

ok.

Answer 13

so its 9.9?

Answer 14

@Mertsj ?

Answer 15

\[x=7\sqrt{2}=7(1.414)=9.9\]

Answer 16

i am so confused.

Answer 17

What are you confused about?

Answer 18

the answer, is it x = 7√2 = 7(1.414) = 9.9?
or is it 9.9

Answer 19

Do you notice the equal signs between those numbers?

Answer 20

mertsj, im not very smart. and yes i do.

Answer 21

What do those equal signs mean?

Answer 22

it means their the same? but what is the same? 7√2 = 7(1.414) and 9.9?

Answer 23

Yes. those numbers are the same number but they are in different forms. What form does your problem say you should use?

Answer 24

radical form.

Answer 25

so the answer is 7√2 = 7(1.414)

Answer 26

I guess I'm having trouble reading because I thought it said "write your answers as integers or decimals rounded to the nearest tenth."

Answer 27

oh poop, wrong problem.

Answer 28
