ololo11 [35]

Answer:

sin S =  is the ratio found.

Step-by-step explanation:

It is given that m∠U = 90°

TS is the hypotenuse = 73 units

UT is the adjacent side of the right angle = 48 units

SU is the base of the triangle = 55 units

Now we have to find the ratio as,

sin S =

sin S =

Plugin the values, we will get,

sin S =

So the ratio was found.

I need someone to teach me how to do at least half of these problems please help
Gwar [14]
Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.

75) Here, oly option D can fit i the equation, we can check:
 3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.

76) Here, only option D is your answer, 
4(2) - 4 = 8 - 4 = R.H.S

Do the same thing in every equation!

Hope this helps!
