Answer:
15 degrees
Step-by-step explanation:
So you know that the sum of the two angles is 90 degrees, so you can make an equation:
Then, solve:
subtract 45 from both sides
divide both sides by 3
This means that x = 15 degrees
Answer:
Step-by-step explanation:
(7^0/7^5)^1/5
= (1 / 7^5)^ 1/5
= (7^-5)^1/5
= 7^-1
= 1/7 is the correct answer.
Answer:
5
Step-by-step explanation:
-4 = x - 9

4x + 10 = -26
-10 -10
4x = -36
Then -36 divided by 4
X= -9 -9 is the answer.
Answer:
second choice
Step-by-step explanation:
The given sums ∑ have j = 1, j = 2, j = 3, j = 4, j = 5
Consider first j = 1 and substitute in the answers to see if we get the first term of the series -3
✅
2·1 - 5 = 2-5 = -3 ✅
3·1 - 6 = 3-6 = -3 ✅
❌
We see that last choice gives us as first term to be 1 not -3 so eliminate that possibility.
Consider now j = 2 and substitute in the answers to see if we get the second term of the series -1
✅
2·2 - 5 = 4-5 = -1 ✅
3·2 - 6 = 6-6 = 0 ❌
We see that third choice gives us as second term to be 0 not -1 so eliminate that possibility.
Consider now j = 3 and substitute in the answers to see if we get the third term of the series 1
❌
2·3 - 5 = 6-5 = 1 ✅
We see that first choice gives us as third term to be -1/3 not 1 so eliminate that possibility.
Now we are left with the second choice as the only possibility.
