The triangles are similar. What is the value of x? Enter your answer in the box. x = two right triangles. the larger triangle ha
s a longer leg measuring 48 units, smaller leg measuring 20 units, and a hypotenuse measuring 52 units. the smaller triangle has a longer leg measuring 12 units, smaller leg measuring 5 units, and x on the hypotenuse.

I'll do a similar problem, and I challenge you to do this on your own using similar methods!
x+5y+2z=23
8x+4y+3z=12
9x-3y-7z=-10
Multiplying the first equation by -8 and adding it to the second one (to get rid of the x) and also multiplying the first equation by -9 and adding the third one to get rid of the x there too, we end up with
-36y-13z=-92
and
-48y-25z=-217
Multiplying both equations by -1, we get
36y+13z=-92
48y+25z=217
Multiplying the (new) first equation by -4/3 and adding it to the second (to get rid of the y), we get
(7+2/3)z=94+1/3
Dividing both sides by (7+2/3) to separate the z, we get
z=
Plugging that into
48y+25z=217, we can subtract 25z from both sides and divide by 48 to get
Lastly, we plug this into x+5y+2z=23 to get
x=23-5y-2z by subtracting 5y+2z from both sides to get
Good luck, and feel free to ask with any questions!
