Given:
The pairs of angles are:
36°,24°
18°,72°
96°,84°
To find:
Whether each pair of angle measurements are complementary, supplementary or neither.
Solution:
Two angles are complementary if there sum is 90 degrees.
Two angles are supplementary if there sum is 180 degrees.
For 36° and 24°,
So, this pair is neither complementary not supplementary.
For 18° and 72°,
So, this pair is complementary.
For 96° and 84°,
So, this pair is supplementary.
Derivatives:
cos --> -sin
sin ----> cos
f' = cost - sint
f ' (pi) = cos(pi) - sin(pi)
= -1 -0
= -1
Answer:
9
Step-by-step explanation:
Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:
a-7=2
Add 7 to both sides:
a-7+7=2+7
a=9

Let's say we had to multiply the two binomials (x + 1)(x + 2). We could use the grid method or FOIL, but we will use the grid method for now. Here is how you do it:
1. Identify all the terms in the expression:
x, 1, x, 2
2. Align the terms in a grid-like fashion according to their binomials:
x 1
x
2
3. Now, multiply all the terms together (ex. x × x is x²)
x 1
x x² 1x
2 2x 2
4. Put all products in decreasing order:
x²+1x+2x+2
5. Combine Like Terms (CLT):
x² + 3x + 2
Therefore, the answer is x² + 3x + 2. As you can see, the grid method is figuratively long, and the FOIL method is definitely recommended. Hope this helped!
