Question

Analyze the diagram below and complete the instructions that follow. Find Sin

Answer 1

For this case we have by definition, the sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle. Then, according to the figure we have:

$Sin (A) = \frac {8} {10}$

Simplifying we have to:

$Sin (A) = \frac {4} {5}$

Answer:

Option B

Answer 2

Sin is the measure of the opposite leg over the hypotenuse from the given angle:

opposite/hypotenuse

We must find the sin of Angle A, and in order to do so we must find the opposite leg and hypotenuse:

opposite leg/hypotenuse

8/10

Simplify:

8/10 = 4/5

Hence, the sin of <A is 4/5
