Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees.So 180÷2=90;90÷2=45;180÷6=30 and 90÷6=15.Altough the answer is A.
Answer:
7
Step-by-step explanation:
This operation is identical to subtracting 6 from 13. The correct result is 7.
Answer:
First lets find the area of the bottom circle:
7.2 is your radius so:
7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.
lets continue:
51.84 x 3.14(pi) = 162.7776
Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.
2 x 3.14 x 7.2 = 45.216
Now lets multiply it by the height:
45.216 x 17 = 768.672
Now lets add both areas:
768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.
The answer is the second answer choice, an = -13 + 5(n - 1)
Given:
Solution:
Complex formula:
Let us simplify one by one.
|3 + 4i| = 5
|3 - 4i| = 5
|-3 + 4i| = 5
|-3 - 4i| = 5
Substitute these in the given expression:
The solution of the expression is 20.
