Question

Find y. Y=

Answer 1

Man hurry up

Answer 2

ok what do u know about traingles

Answer 3

especailly this kind of traingle

Answer 4

Right angle

Answer 5

Please

Answer 6

m here im here

Answer 7

and how much does a right angle equal

Answer 8

so you know how i helped you on the last one?
y is going to be the longest side so
7^2+x^2=y^2

Answer 9

so y is going to be a bigger number than 7, i forgot how to figure it out with angles- but if you want the last angle add the angles up and minus it from 180 because triangles angles always add up to 180

Answer 10

Yes. The long side is called the hypotenuse and it can be found using the pythagorean theorem.

\[a ^{2}+b^{2}=c ^{2}\]

where a and b are the sides of the triangle and the c is the hypotenuse.

Answer 11

thats what i just said- now shoo pls

Answer 12

??? I'm literally just trying to help

Answer 13

ik but i just said that-

Answer 14

I"m not saying you're wrong, I was simply providing additional information and formatting it in a different way since I know up carets can be confusing to look at.

Answer 15

i help them with their last one-

Answer 16

We're not using the pythagorean theorem to find x and y tho-

Answer 17

ik but it works the same way tho okay? i forgot how yto do it withthe angles

Answer 18

You have to use those trig ratios \[sin(\theta)=\frac{opposite}{hypotenuse}\\cos(\theta)=\frac{adjacent}{hypotenuse}\\tan(\theta)=\frac{opposite}{adjacent}\]
in this case, 45 is the reference angle, s is adjacent, y is hypotenuse, and 7 is opposite

Answer 19

Is there more need for help here?

Answer 20

no

Answer 21

Ok :D

Answer 22

well, yes, 45 45 90 degree triangle makes it 1, 1, sqrt2

Answer 23

littleduckling wasn't the one who asked the question :|

Answer 24

Oh lol. So what is the current problem?

Answer 25

they're not online- you don't know what they're thinking, but alright
