For this case we must solve the following system of equations:
To solve we follow the steps below:
We multiply the second equation by -3:
Thus, we have the equivalent system:
We add the equations:
We look for the value of the variable "y":
Thus, the solution of the system is given by:
Answer:
You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
Answer:
Step-by-step explanation:
lets say you have two negative numbers, -x and -y (x and y are positive).
-8y = -4x + 16
Y = 4/8x - 2
Answer:
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
