Answer:

\tan A

Step-by-step explanation:

From the diagram, side length a is opposite to angle A and side length c is adjacent  to angle A.

Recall the mnemonics SOH CAH TOA.

We use TOA, because it involves opposite and adjacent.

\tan A=\frac{Opposite}{Adjacent}

\tan A=\frac{a}{c}

The correct choice is A.

<h2>Hello!</h2>

The answer is:  A. Tan(A)

<h2>Why?</h2>

Since it's a right triangle, we must remember the following trigonometric identities:

sin\alpha =\frac{opposite}{hypotenuse}\\\\cos\alpha =\frac{adjacent}{hypotenuse}\\\\tan\alpha=\frac{opposite}{adjacent}

We are going to work with the tangent indentity, so:

If we are looking which a trigonometric ratio/relation which is equal to:

\frac{a}{c}

Also, from the image we can see that:

opposite=a\\adjacent=c\\hypotenuse=b

So, using the tangent identity, which is equal to:

tan(A)=\frac{opposite}{adjacent}=\frac{a}{c}

So, the correct option is A. Tan(A)

Have a nice day!

Measure of angle A???
Rudik [331]

Answer:

A

Step-by-step explanation:

The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.

A property of equilateral triangles is the angles are congruent.

The sum of the 3 angles = 180°, hence the measure of each angle is

\frac{180}{3} = 60° → A

What are the side lengths of the equilateral triangle?
Alchen [17]

5x  +  (6x - 5) + (3x + 10) = 360

5x  + 6x - 5 + 3x + 10 = 360

11x - 5 + 3x + 10 = 360

14x + 5 = 360

14x = 360 - 5

14x = 355

x = 25.36

x = 25.36

5x = 5 \times 25.36 = 126.8

6x - 5 = 6 \times 25.36 - 5 = 147.16

3x + 10 = 3 \times 25.36 + 10 = 86.08
