The answer is 73 ounces. the gift weights 64 ounces ( 4 pounds ) alone and 64+9=73. *1 pounds = 16 ounces
39 + 68 + x = 180
107 + x = 180
x = 73
your answer is actually C. 73
Picturing the tent helps, but we can actually solve this question using simple algebra and no knowledge of triangles.
The key is this function:
(b/h) = 2/√3
We want to get h by itself. First, multiply both sides by h:
b = h(2/√3) Now multiply both sides by the reciprical, (√3/2)
(√3/2) b = h
Therefore, the answer is C) h= b(√3/2)
Answer:
The triangle is acute because all of the angles are less than 90º
