Find X AND Y! pleas help me! only reply if you KNOW IT thank you
lawyer [7]

The measures of the legs of the right triangle are:

X = 2.5

Y = 4.3

<h3>How to find the values of x and y?</h3>

In the image, we can see a right triangle with a hypotenuse with a value of 5, and a known angle.

To find the values of X and Y (the legs of the triangle) we can use the two relations:

Sin(a) = (opposite cathetus)/(hypotenuse)

Cos(a) = (adjacent cathetus)/(hypotenuse)

In this case, we have:

a = 30°

hypotenuse  = 5

opposite cathetus = X

adjacent cathetus = Y.

Replacing that in the relations we get:

Sin(30°) = X/5

Sin(30°)*5 = X = 2.5

cos(30°) = Y/5

cos(30°)*5 = Y = 4.3

Evaluate 8(7x--3) when x=9
Schach [20]

I will assume that by "Evaluate 8(7x--3) when x=9" you meant:

"Evaluate 8(7x-3) when x=9."

First, substitute 9 for x in 7x-3: 7(9)-3 = 60. Rewrite the problem as:

8(60). Multiply. Answer: 480
