Answer:

The answer is option B.

Step-by-step explanation:

To find Angle A we use cosine

cos ∅ = adjacent / hypotenuse

From the question

The adjacent is 14

The hypotenuse is 26

So we have

cos A = 14/26

cos A = 7/13

A = cos-¹ 7/13

A = 57.42

<h3 /><h3>A = 57° to the nearest degree</h3>

Hope this helps you

Answer:

57 deg

Step-by-step explanation:

(see attached for reference)

we are given a right triangle together with the lengths of one side (= 14 units) and the hypotenuse (= 26 units)

Using the trigonometry formulas, we can find angle A

cos A = adjacent length / hypotenuse

cos A = 14 / 26

A = cos⁻¹ (14/26) (use calculator)

A = 57.42 deg

A = 57 deg (rounded to nearest whole degree)

Selling Price is $2,640 and the Loss is $196. Find the Cost Price.

myrzilka [38]

If I am correct, it should be $2,736.

if this is a re-sell, then you would have to add the loss to the selling price to get the original cost.

loss means how much was lost in profit, so whenever you see that make sure to add it to whatever is applicable, like in this case, $2,640.
