Bob says that he can find the area of the triangle below using the formula: A = * 8 *18 * sin (120°). Is he correct? Explain why or why not.

No.

Step-by-step explanation:

No, Bob is not correct.

The formula he's using is the following:

The important thing here is that the angle is between the two sides.

In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.

Either Bob needs to find the other side first or find the angle between 8 and 18.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
