8 0

Answer:

x = 85

Step-by-step explanation:

Because this is a right triangle, we can use the Pythagorean Theorem:

a² + b² = c²

Where c is the hypotenuse, or the longest side. This is opposite to the right angle of the right triangle. So now you have:

84² + 13² = x²

7056 + 169 = x²

7225 = x²

√7225 = √x²

85 = x

x = 85

Given sin y = -4/5, where π < y < 3π/2, and cos x = 12/13, where 0 < x < π/2. Find the exact value of sin (x - y).

konstantin123 [22]

Answer:

Solution given:

sin y = -4/5

p/h=4/5

p=4

h=5

b=√{5²-4²)=3

cos y = b/h=-3/5

again

cos x=12/13

b/h=12/13

b=12

h=13

p=√(13²-12²)=5

sin x=p/h=5/13

now

sin[x-y]=sinxcosy-cosxsiny

=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.
