Answer:
5m
Use the Pythagorean theorem: base =sqrt(13^2-12^2)= sqrt(25) =5
sqrt Is Square root btw
Step-by-step explanation:
The given system of equations are ,
- -3x + 3y = 3
- -5x + y = 13
<u>Solving</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>:</u><u>-</u><u> </u>
=> -3x + 3y = 3
=> -3( x - y ) = 3
=> x - y = 3/-3
=> x - y = -1
=> x = y + 1
<u>Put </u><u>this </u><u>value </u><u>in </u><u>(</u><u>2</u><u>)</u><u> </u>
=> -5(y+1) + y = 13
=> -5y -5 + y = 13
=> -4y = 18
=> y = 18/-4
=> y = -9/2 = -4.5
<u>Finding</u><u> </u><u>x </u><u>:</u><u>-</u><u> </u>
=> x = -4.5 + 1
=> x = -3.5
<h3>
Hence the value of x is -3.5 and y is -4.5</h3>
