Answer: D. 3 x 10^7
Step-by-step explanation: 9.6/3.2=3 and 10^9/10^2 is 9-2=7, so 10^7, so it would be 3 x 10^7.
V = L * W * H
V = 4 * 4 * 8
V = 16 * 8
V = 128 cubic ft
Answer:
These two lines that are running horizontally are parallel lines.
The angle with measure 115 degrees is congruent to angle 2 (by the law of parallel lines).
So, if these two angles are congruent, angle 2 is also 115 degrees.
Let me know if this helps!
Answer:
Sine, cosine and tangent formulas are used in RIGHT triangles. So you have one 90 degree angle and two acute angles that add up to 90 degrees (they are complimentary). So the cosine of one angle would be the same as the sine of the compliment to that angle... and vice versa. To answer this question, sin 81 = cos 9, since 81 and 9 are the two acute angles of the triangle and they both add up to 90 degrees. "Cos 9" is the answer when you wish to write "sin 81" in terms of "cosine."
