There is many way how to get the length of a triangle. You can use many method but to your question the best method to use is Law of sine and cosine Side Angle Side triangle formula. This formula is this one (a^2 = b^+c^2-2bc*cos(angle)). So if your fill it up it would be (a^2 = 3^2+4^2-2*3*4*cos(60)). The answer would be 3.61

we have the inequality
![\lvert5x+4\rvert\leq10](https://tex.z-dn.net/?f=%5Clvert5x%2B4%5Crvert%5Cleq10)
step 1
Find out the first solution (positive case)
![\begin{gathered} +(5x+4)\leq10 \\ 5x\leq10-4 \\ 5x\leq6 \\ x\leq\frac{6}{5} \\ x\leq1.20 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%2B%285x%2B4%29%5Cleq10%20%5C%5C%205x%5Cleq10-4%20%5C%5C%205x%5Cleq6%20%5C%5C%20x%5Cleq%5Cfrac%7B6%7D%7B5%7D%20%5C%5C%20x%5Cleq1.20%20%5Cend%7Bgathered%7D)
The first solution is all real numbers less than or equal to 1.20
Interval (-infinite,1.20]
step 2
Find out the second solution (negative case)
![-(5x+4)\leq10](https://tex.z-dn.net/?f=-%285x%2B4%29%5Cleq10)
Multiply by -1 both sides
![\begin{gathered} (5x+4)\ge-10 \\ 5x\ge-10-4 \\ 5x\ge-14 \\ x\ge-\frac{14}{5} \\ x\ge-2.8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%285x%2B4%29%5Cge-10%20%5C%5C%205x%5Cge-10-4%20%5C%5C%205x%5Cge-14%20%5C%5C%20x%5Cge-%5Cfrac%7B14%7D%7B5%7D%20%5C%5C%20x%5Cge-2.8%20%5Cend%7Bgathered%7D)
The second solution is all real numbers greater than or equal to -2.8
the interval [-2.8, infinite)
step 3
Find out the solution to the given inequality
The solution is
[-2.8, infinite) ∩ (-infinite,1.20]=[-2.8,1.20]
the solution is the interval [-2.8,1.20]
see the attached figure to better understand the problem
Answer:
the answer to that is -1i
Step-by-step explanation:
cause if you add negative and positve you get to subtract it and get the sign of the highest number
