Answer:

x ≈ 2.3 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos55° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{4}$ ( multiply both sides by 4 )

4 × cos55° = x , thus

x ≈ 2.3 cm ( to 1 dec. place )

Find the value of f. What can you do to Both Sides?f - ⅔ = ¼

Thepotemich [5.8K]

Answer:

11/12

Step-by-step explanation:

<h2><u>Value of F </u></h2>

to find the value of f , we need to move the -2/3 to the other side of the equal sign.

$f - \frac{2}{3} = \frac{1}{4}$

<u><em>Note </em></u>: is you move a number from one side of the equal sign to the other, this changes the sign of the number ( eg , -2/3 becomes +2/3)

$f = \frac{1}{4} + \frac{2}{3}$

f = $\frac{11}{12}$

<h3><u>hence the value of f is 11/12 </u></h3>
