Mathematics

SOVA2 [1]3 years ago
5 0

Answer:

x = 20

Step-by-step explanation:

By exterior angle theorem, we have:

(4x + 2) \degree + (2x  - 9) \degree = (5x + 13) \degree \\  \\(4x + 2 + 2x - 9) \degree  = (5x + 13) \degree\\  \\(6x  - 7) \degree  = (5x + 13) \degree \\  \\ 6x - 7 = 5x + 13 \\  \\ 6x - 5x = 13 + 7 \\  \\ x = 20

What is the value of y?<br><br> Enter your answer, as an exact value, in the box.
Amanda [17]
So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.

--> a changed into a√2
√2 changed in √2 * √2
= 2

So the hypotenuse of the 40-40-90 degree triangle is 2.

Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.

-> a is changed to a√3
2 is changed into 2√3


So, y is 2√3 or approximately 3.46 units.

Graph the system of equations on graph paper to answer the question. Y=2/5x+4 and y=2x+12 what is the solution for this system o
riadik2000 [5.3K]

Answer:

Solution of the given equations is (-5,2)

Step-by-step explanation:

We have been given the following system of equations:

y = (2/5)x + 4

y = 2x + 12

The solution of the system of equation can be found by finding the point of intersection of both lines on the graph. The graph of both equations is attached below.

As we can see that both the lines intersect each other at one point, and that point is (-5,2). So the solution of the given equations is (-5,2)
