Alright so these ratios have many different forms but the way I use to remember the trigonometric ratios is:
SOH
CAH
TOA
This means:
Sine --> Opposite/Hypotenuse
Cosine --> Adjacent/Hypotenuse
Tangent --> Oppositie/Adjacent
With that in mind, number 1:
Would be Sine, or C.
Number 2 would be, Cosine, or E.
And number 3 would be Tangent, or B.
Hope that was helpful.
X= 1 number
Y= a number that is 1 less than x
Y= x-1
The sum of squares=
X^2 + (x-1)^2 = x^2 + x^2 - 2x + 1
X^2 + x^2 - 2x + 1 = 2x^2 - 2x + 1
Assuming that integers = numbers. We could try some values
When x = 0, the sum of squares = 1
When x = -1, the sum of squares = 4
When x = 1, the sum of squares = 1
If you put this into a graph, it is a parabola and we see that the minimum value hits at x = 1/2.
To check this value:
2x^2 - 2x + 1 = 2·(1/4) - 2·(1/2) + 1
2·(1/4) - 2·(1/2) + 1 = 1/2 - 1 + 1
1/2 - 1 + 1 = 1/2
When you look back at the question, it asks for 2 answers
X= 1/2
X-1 = -1/2
What is the sum of their squares?
1/4 + 1/4 = 1/2
That fits with graph too.
Answers: 1/2 and -1/2
Hope this helps!!
Answer :
7 unitsThere are two ways you can solve this problem:
1st way - Subtract the T's x coordinate by r's x coordinate.
1-(-6) = 1+6 =
7
2nd way - Graph the points than count the units between them.

Answer:
B = 53.13
Step-by-step explanation:
Since this is a right triangle, we can use the tan function
tan B = opposite side/ adjacent side
tan B = 4/3
Take the inverse tan of each side
tan ^-1 (tan B) = tan^-1 (4/3)
B = 53.13010235
To the nearest hundredth
B = 53.13
