The answer is is 4.2
3^2+3^2=c^2
9+9=c^2
18=c^2
Square root both sides
4.242640687119285=c
Answer: x=(7√6)/2
Step-by-step explanation:
To find x, we would have to find the hypotenuse of the 45-45-90 triangle. First, we would have to find the hypotenuse by using the 30-60-90 triangle on top to find it.
For a 30-60-90 triangle, the hypotenuse is 2x in length. the x is the same in all sides. All you would have to do is to plug it in. The leg opposite of 60° is x√3 in length. the leg opposite of 30° is x in length.
Since we know that 7 is opposite of the 30° angle, we know that x is 7. Across fron 60° is the hypotenuse of the 45-45-90 triangle. That leg is x√3. We plug in x=7 and get 7√3.
The hypotenuse of the 45-45-90 triangle is x√2 and the legs are both x. We can set 7√3 equal to x√2 to find x of the missing side.
7√3=x√2 [divide both sides by √2]
x=(7√6)/2
Now, we know x=(7√6)/2.

9i√2
-18
so therefore the answer is 9i√2
Answer:
-6/8
Step-by-step explanation:
The slope formula is y2-y1
____
x2-x1
In the ordered pair (-20,4)
-20 is x1 the first x and 4 is x1
-12 is the x2 i.e. 2nd point and -10 is y2 i.e. 2nd point on y axis
so we plug in the value to the formula -10-(-4) two negatives become +
_____
-12-(-20)
so -10+4 -6 6
____ = ___ = - _
-12+20 8 8
(remember you subtract and the signs are different you subtract and use the sign of larger number)
