Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of si

n x° and cos y° share? A right triangle is shown with one leg measuring 4 and another leg measuring 3. The angle across from the leg measuring 3 is marked x degrees, and the angle across from the leg measuring 4 is marked y degrees.

Sin=opposite side/hypotenuse

So let's first find the hypotenuse using pythagoras theorem 4²+3²=H² so H=5

Sin x=3/5

Cos=adjacent side/hypotenuse

Cos y=3/5

So the relationship is that both are the same value, hope it helps cheers!

Plz help for exam!!!<br> Solve for x and y.
ad-work [718]

Answer:

A x-198,y-99\sqrt{3}

Step-by-step explanation:

since sin p/h you can say

perpendicular is 99

and hypotenuse is x

sin 30=99/x

x=198

and cos is b/h

base is y

and hypotenuse is x

cos 30=y/198

y-99\sqrt{3}

Math question down below
Kipish [7]
Answer: 6928

----------------------------------------------------------

Explanation: 

We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.

Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000

Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072

Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928

This difference D is exactly equal to the shaded area.

The ratio of apples to bananas in a bowl of fruit is 2:5 if there are 49 total pieces of fruit in the bowl how many are apples
Ghella [55]

14 apples because altogether the ratio adds up to 7 and 49/7=7 so we could rewrite the ratio as 2x:5x so x=7.  there for 2x ,the number of apples is 14
