Answer:
45.55 m
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship between adjacent and opposite sides of an angle is ...
Tan = Opposite/Adjacent
Then the side opposite the angle of elevation will have length ...
tan(26°) = Opposite/(90 m)
Opposite = (90 m)·tan(26°) ≈ 43.90 m
This is the height of the top of the dam above Scarlett's height, so the total height to the top of the dam is ...
43.90 m + 1.65 m = 45.55 m
Answer:
A=61.5cm^2
Step-by-step explanation:
Area= 5*1/2(lh)
A=5*1/2(6*4.1)
A=5*1/2*24.6
A=5*12.3
A=61.5cm^2
Answer:
24, 48, 108
Step-by-step explanation:
2:9:4
2x+9x+4x=180
15x=180
x=12
2(12)=24
9(12)=108
4(12)=48
Hello there! I can help you! In order to answer those questions, we need to plug in the values, based off of the variable.
g. Okay. We are solving b - 10. b = -8. When you subtract something from a negative number, the number is even lower. Let's add the numbers first and then put in the negative symbol. 8 + 10 is 18. Put the negative sign and you get -18. The difference is -18.
h. Now, we solve a - b. a = 5 and b = -8. Because we are subtracting a negative number from a positive, we have to add both numbers, which means the number gets bigger. Ignore the negative sign and add. 5 + 8 is 13. There. The sum is 13.
i. The problem is c - a. c = -9 and a = 5. So as explained on problem G, for this problem, ignore the negative symbol and add. 9 + 5 is 14. Plug in the negative sign to get -14. There. The difference is -14.
