Question

Solve triangle XYZ if m 11 years ago

Answer 1

I believe this uses the law of sines.

Answer 2

All triangle add up to 180, so 39 + 88 + x = 180 solve for x

Answer 3

yeap... pretty much.. notice you have angle Y and side y

Answer 4

Select one:
a.
x= 53°, y= 88°, z= 39°, x ≈ 57, y = 70, and z ≈ 44.1
b.
x = 53°, y= 88°, z= 39°, x ≈ 55.9, y = 70, and z ≈ 45
c.
x= 53°, y = 88°, z= 39°, x ≈ 44, y = 70, and z ≈ 56
d.
x = 53°, y = 88°, z = 39°, x ≈ 55.9, y = 70, and z ≈ 44.1

Answer 5

This is what it gives for the answers.

Answer 6

This is a tricky one, drawing it out might help you solve it.

Answer 7

\(\bf \cfrac{sin(Z)}{z}=\cfrac{sin(Y)}{y}\implies y=?\)

Answer 8

This guys smarter listen to him >.>

Answer 9

haemm actually we have y so \(\bf \cfrac{sin(Z)}{z}=\cfrac{sin(Y)}{y}\implies z=?\)

Answer 10

Im confused. I entered in the info and I dunno how to use what I got.

Answer 11

For the first one with sinz I got 55.38. then for the second I got 38.97.

Answer 12

well... when solving for "z" what would that give you then?

Answer 13

I dunno would I add the two numbers I got together or what?

Answer 14

well.. you'd want to "solve for z" first.... just a linear simplification
and then plug in the numbers

Answer 15

Again I don't know what you mean.

Answer 16

well.. is just two fractions... so you'd just firstly need to solve for "z" \(\bf \cfrac{sin(Z)}{z}=\cfrac{sin(Y)}{y}\implies z=\cfrac{\square ?}{\square ?}\)

Answer 17

So I would put 55.38/38.9 then?

Answer 18

well... ... you'd need to simplify for "z" first

Answer 19

And how would I do that?

Answer 20

hmmm well there seems to be an assumption you should know that
you can brush up your simplification though -> https://www.youtube.com/watch?v=n3FbQGGKVfc

Answer 21

I still don't know what I need to simplify.

Answer 22

@BaltM here is reference to help with learning how to use law of sines

Answer 23

Thanks. That's all I needed to know.
