Your answer will be -9 !!
Answer:
B. 22
Step-by-step explanation:
We know tan60=

Let common side be x
Tan = opp/adj= sqrt(3)

Transposing we get :

Now, we know that since the other triangle is a 45-45-90 triangle, we can state that the side adjacent to the given angle = 11 sqrt(2) as the two sides are equal due to the triangle being an isoceles triangle.
Solve for x by using Pythagorean theorem:



Hence answer is B. 22
Answer:
10 13/21
Step-by-step explanation:
Convert mixed numbers into improper fractions
4 9/14 --> 65/14
2 6/7 --> 20/7
8 5/6 --> 53/6
Then calculate
65/14 - 20/7 + 53/6
Before that write it into a common denominator of 42
(195-120+371)/42
That would equal to 446/42
Divide it by 2
That would equal to 223/21
Then 223/21 = 10 13/21
P.S!!!
Don't blindly trust me, check before with others

Answer:
Step-by-step explanation:
For this, we kind of have to test points to solve it. First, we can test theh interval x<= -2. Plug in -2 and we get a negative value which works. Next, let's try -2<x<0. Plug in -1 and get a positive value which doesn't work.
Next try 0<=x<=7. Plug in any number like 4 and get a negative value which works.
Finally, try x>7. Plug in 8 for example and you would get a positive value. So the solution is
x <= -2 OR 0 <= x <= 7
