I think you would multiply 4 12/90 by 9 which equals 37 1/5
The ratios of sin x° and cos y° are 15/8.
We have given that,
Use the image below to answer the following question.
We have to determine to find the value of sin x° and cos y°.
By applying Pythagoras theorem in the triangle given in the picture,
<h3>What is
the Pythagoras theorem?</h3>
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying the sine rule in the given triangle,
sin(x°) = Opposie side/hypotenous
= 15/17
cos(y°) = Adjucent side/hypotenous
= 8/17
The relation between the ratio of sin(x) and cos(x) will be,


Therefore the ratios of sin x° and cos y° are 15/8.

It’s a
100-25= 75
75 divided by 0.01
0.75 x 18
Step-by-step explanation:
{9x+3y=-36
y=-3x-21
9x-9x-36=-36
y=-3x-21
x=0
y=-21
An average triangle has an exact angle of 180.
The sum of these listed numbers is 180. So, you can make exactly 1 triangle.
I hope this helps!
