Answer:
12.69 inches.
Step-by-step explanation:
Let h represent the length of the hypotenuse.
We have been given that a right triangle contains a 38° angle whose adjacent side measures 10 centimeters. We are asked to find the length of the hypotenuse.
We know that cosine relates adjacent side to hypotenuse of right triangle.
Upon rounding to the nearest hundredth of a centimeter, we will get:
Therefore, the length of the hypotenuse is approximately 12.69 inches.
