Answer:

The answer is option B.

<h2>57°</h2>

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)
