<h3>Answer:</h3>

47.10

<h3>Step-by-step explanation:</h3>

The mnemonic SOH CAH TOA reminds you that ...

... Cos = Adjacent/Hypotenuse

The value y is the length of the hypotenuse, and the given length 35 is the side adjacent to the given angle. Thus, the cosine relationship will be helpful.

Filling in the given values, we have ...

... cos(42°) = 35/y

Multiplying by y/cos(42°), we can find y to be ...

... y = 35/cos(42°) ≈ 35/0.7431

... y ≈ 47.10

Answer:

Y will be approximately  47.10 in length

Step-by-step explanation:

  • we will use this  form that we memorized in our schools ............. SOH CAH TOA

<em>CAH means , </em> Cos ∅= Adjacent/Hypotenuse

  • Given values

∅ =42°

hypotenuse= y

adjacent side length = 35

  • now putting in our values  into

Cos ∅= Adjacent/Hypotenuse

OR

cos(42°) = 35/y

  • by multiplying y on both sides we get

y= 35/cos( 42°)

  • cos(42°)= 0.743

so  y= 35/0.743    

y = 47.10632

OR

  • y ≈ 47.10

In the triangle below, y= . Round to the nearest tenth
horsena [70]

Use cosine.

cosine={adjacent}{hypotenuse}

We have:

adjacent = 9cm and hypotenuse = 17 cm

\cos x=\dfrac{9}{17}\approx0.5294\to x\approx58^o
