Answer:
60°
Step-by-step explanation:
We'll begin by calculating EC. This can be obtained as follow:
Angle EAC = 39°
Hypothenus = EA = 3.7 m
Opposite = EC =?
Sine EAC = Opposite /Hypothenus
Sine 39 = EC / 3.7
Cross multiply
EC = 3.7 × Sine 39
EC = 2.3 m
Finally, we shall determine angle BEC. This can be obtained as follow:
Adjacent = EC = 2.3 m
Hypothenus = BC = 4.6 m
Angle BEC =?
Cos BEC = Adjacent / Hypothenus
Cos BEC = 2.3 / 4.6
Cos BEC = 0.5
Take the inverse of Cos
BEC = Cos¯¹ 0.5
BEC = 60°
Thus, angle BEC is 60°
Answer:
It will be any graphs that show a parallel line relationship.
Explanation:
Any graph that shows parallel lines will always be no solution.
Okay, so let's go over multiplying negative numbers. A positive times a positive is a positive, right? But a negative times a negative is also a positive. Only a negative times a positive (or a positive times a negative) gives you a negative number. So, we know that one of our 2 numbers in this question must be negative; the other must be positive.
Let's now take a look at the factors of -147, starting with the positives. Obviously, -147 and 1 are factors: -147 * 1 = -147. What other factors of -147 are there?
What about 7? Try it: -147 / 7 = -21. So here are two factors: -21, and 7. They multiply to -147. Do they add up to -14? Let's see: -21+7 = 7+(-21) = 7-21= -14. Yup, that works!
Answer: -21 and 7
A=-3y/x+48/x

For the answer to the question above, <span>if
a1 = 2,
then
a2 = 3a1 + 1
a3 = 3a2 + 1 = 3
Then, we can finally solve for terms of sequence.
(3a1 + 1) + 1 = 9a1 + 4 = 9(2) + 4 = 22
So the answer to your question is,
</span><span>22, 67, 202, 607
