The tangent of the larger acute angle

The tangent of the larger acute angle is 4/3 or 1⅓

Step-by-step explanation: if the sides of the right angled triangle are given as 3, 4 and 5 respectively, then the hypotenuse is 5 and the longer of the other two sides is 4. The angle facing the side measuring 4 is your reference angle, and that is the larger of the other two acute angles (see attachment)

Tan X = opposite/hypotenuse

Tan X = 4/3

Tan X = 1⅓

answer:

your answer is: c. 196 7/8 in^3.
