Question

Anyone know this?? it’s finding the sine of a triangle!!

Answer 1

Check the picture below.

Answer 2

I'm not sure what you want me to answer from this, so I solved for every variable:

Angle A: 83°

Side b: 6.29

Side c: 5.8

Explanation:

-----Angle A:

Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:

`A+51+46=180\\A+97=180\\A=83`

-----Side b:

Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:

`(a)/(sin(A)) =(b)/(sin(B)) \\(8)/(sin(83)) =(b)/(sin(51)) \\8.06=(b)/(0.78) \\6.29=b`

-----Side c:

`(a)/(sin(A)) =(c)/(sin(C)) \\(8)/(sin(83))=(c)/(sin(46)) \\8.06=(c)/(0.72) \\5.8=c`
