Answer:
Step-by-step explanation:
- First we go to find <u>the length of ZX</u>
- Notice that the angle of 25 degrees is opposite of the side length of 15 and <u>ZX</u> is what were trying to find.
- Set up the equation sin25=15/x
- Now move the 15 to the other side, x*sin25=15
- now use your calculator to find x=35.4930238935
- now find angle x( the triangle on the right)
- notice that we the the side opposite to as 22 and the adjcent as 35.4930238935,we can use the tangent function to find the angle
- set up the equation tanx=22/35.4930238935
- tanx=0.619840114666
- x=tan^-1(0.619840114666)
- x=51.69554°
- now know that a triangle has a total of 180 degrees, now we have the two angles we can make a equation for W to find the angle
- W+51.69554+90=180
- W+51.69554=90
- W=38.30446
<h2>So the final Answer is m of W = 38.30446 degrees.</h2><h2 />

Good evening ,
_______________
2(7) + 5(1) + 3(-3) = 10
3(7) - (1) + 4(-3) = 8
5(7) - 2(1) + 7(-3) = 12
Then (7,1,-3) is a solution to system

Answer:
Step-by-step explanation:
Please find the attachment.
We have been given that ABC is a right triangle with sides of lengths a, b, and c and right angle at C.
To find the side length a, we will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle.
Upon substituting our given values in Pythagoras theorem, we will get:
Take square root of both sides:
Therefore, the length of side 'a' is 
units.
We know that tangent relates opposite side of a right triangle with adjacent side.
We can see that 'a' is opposite side of angle A and 'b' is adjacent side.
Therefore, the value of tan(A) is 
.
