Answer:
Step-by-step explanation:
Let's make a simple equation! It's much, much simpler than you think. Let's look closely.
<h3>Area = Base x Height</h3>
We already know the area, so we can substitute this already.
<h3>72 = Base x Height</h3>
We also know the height, 6.
<h3>72 = Base x 6</h3>
We can now replace "base" as x to make it simpler to solve the equation we made!
<h3>6x = 72</h3><h3>x = 12</h3><h3 /><h2>The base of the parallelogram is 12 inches.</h2>
Answer:
9 inches
Step-by-step explanation:
4 x 3 = 12
so 3 x 3 = 9
M<KPN = 1/2(90+50) = 140/2=70
answer D. 70 (last choice)
Answer:
Option B (35°).
Step-by-step explanation:
To solve this question, the trigonometric identity sin x = cos (90-x) is required. It can also be written as cos x = sin (90-x). It can be seen that this identity holds when the two angles are complementary i.e. they sum up to 90 degrees. Therefore, the answer can be determined by substituting all the options one by one in the identity cos x = sin (20+x). If x=30 degrees, then x+20=50 degrees. 30 and 50 are not complementary. If x=35 degrees, then x+20=55 degrees. 35 and 55 are complementary since their sum is 90 degrees. Therefore, B is the correct choice!!!
