Answer:
x+3
Step-by-step explanation:
notice how each time you add three
how did I khew that we add 3?
simply by substracting a term from the next one
so 8-5= 3
Check the picture below.
this is a case of the ambiguous case with an SSA, AC and CB are the sides and the angle is at A.
the ambiguous case has two triangles, the case when B is acute, CB sticks out, and the case when B is obtuse, CB sticks inside, it just so happen that those two angles for B are "supplementary" angles.
if you check the sin⁻¹ of that, we'll get the acute version of B, that's because of the constraints on the range of the inverse sine function, and we get ∡B ≈ 36.86989765°.
and of course, the other angle for B will be 180 - 36.86989765.
Answer:
![d_R_T=10\ units](https://tex.z-dn.net/?f=d_R_T%3D10%5C%20units)
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
we have the coordinates
R(−7, 3) and T(3, 3)
substitute in the formula
![d=\sqrt{(3-3)^{2}+(3+7)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%283-3%29%5E%7B2%7D%2B%283%2B7%29%5E%7B2%7D%7D)
![d=\sqrt{(0)^{2}+(10)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%280%29%5E%7B2%7D%2B%2810%29%5E%7B2%7D%7D)
![d_R_T=10\ units](https://tex.z-dn.net/?f=d_R_T%3D10%5C%20units)
Answer:
B
Step-by-step explanation:
Given
x² - 18x + --- = 4 + ----
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + 81 = 4 + 81
(x - 9)² = 85 ( take the square root of both sides )
x - 9 = ±
( add 9 to both sides )
x = 9 ±
← exact solutions
I think it would be -1.
I believe this because it is the biggest negative integer without going to 0 or positive integers.
...if that makes sense.
