Answer:
Answer A
Step-by-step explanation:
Angle A = 180 - 26 - 90 (90 right angle)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos ( A)= adj/hyp
Cos (26) = a / 13
a = 13* Cos (26)
a= 11.7
Find the last side of the triangle using the Pythagorean theorem.
Answer:
4 feet.
Step-by-step explanation:
Please consider the complete question.
Angela makes a pillow in the shape of a wedge to use for watching tv. The pillow is filled with 12 cubic feet of fluffy material. The base is 3 ft, the height is 2 ft. What is the length measure?
We know that a wedge is in form of triangular prism, so the volume of wedge will be equal to volume of triangular prism.
Upon substituting our given values in above formula, we will get:
Therefore, the length of the pillow is 4 feet.
