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
Firstly u need to make equation in formula of y=ax+b
Here we have -x+y=16
When you take x to other side you must change sign of it
Then y=16+x
Y=x+16
I hope u learn

Step-by-step explanation:
The answer would be 25200
Reason being because there is a number of ways when selecting (3 consonants out of 7) and (2 vowels out of 4)
= (7C3 x 4C2)
= 7 x 6 x 5 /3 x 2 x 1 x 4 x 3/ 2 x 1
= 210.
The number of groups each having 3 consonants and 2 vowels = 210.
Because each group contains 5 letters.
They have to be rearranged
5 letters among themselves = 5!
= 5 x 4 x 3 x 2 x 1
= 120.
Required number of ways = (210 x 120) = 25200.
