Question

Can someone help please

Consider the triangle below. One of the side lengths is unknown.

Find the length of the unknown side in this triangle, rounding your answer to two decimal places (if necessary).

Answer 1

b = 13.27

Explanation:

b^2 + 7^2 = 15^2

b^2 + 49 = 225

b^2 = 176

b = sqrt(176)

b = sqrt(16 * 11)

b = 4sqrt(11)

b = 13.27

Answer 2

The other side would be 15 meters.
