In ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45. What is the value of the cosine of ∠X to the nearest hundredth?
kotegsom [21]

The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.

Step-by-step explanation:

The given is,

                   In ΔWXY, ∠Y=90°

                        XW = 53

                         YX = 28

                        WY = 45

Step:1

             Ref the attachment,

             Given triangle XWY is right angled triangle.

             Trigonometric ratio's,

                              Cos ∅  = \frac{Adj}{Hyp}    

             For the given attachment, the trigonometric ratio becomes,

                              Cos ∅  = \frac{XY}{XW}.....................................(1)

             Let, ∠X = ∅

             Where, XY = 28

                         XW =  53

             Equation (1) becomes,

                                 Cos ∅  = \frac{28}{53}

                                 Cos ∅ = 0.5283

                                        ∅ = cos^{-1} (0.5283)

                                        ∅ = 58.109°

Result:

          The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.

Courtney had $55 to spend at the fair. She paid $22.50 for rides and $14.25 for lunch and snacks. Courtney says she has $18.25 l
IrinaVladis [17]
She has $55. She spent $22.50 on rides so now she has $32.50 . Then she spends $14.25 on lunch and snack so now she has $18.25.


A. would be wrong because Courtney IS correct, she has $18.25 left.

C. is also wrong because, again, Courtney IS correct.

So the only option left is B and it explains why Courtney is correct.

Option B is the correct answer.

Hope this helps.

What’s the answer PLZ???

11. Take the logarithm, base X.
  a² - ab = 10
Since we are given that b = a - 2, we can substitute for b to get
  a² - a(a -2) = 10
  a² - a² + 2a = 10 . . . . . eliminate parentheses
  a = 5 . . . . . . . . . . . . . . simplify, divide by 2


_____
Check: a² = 5² = 25
  ab = 5·3 = 15
  X^25/X^15 = X^10 . . . . . the answer works
