Answer:

22.6 degrees

Step:

The hypotenuse is 13cm using pythagoras theorem.

Now, finding the smallest angle is by using;

Answer:

$x=6.25\\y=-1.25$

Step-by-step explanation:

$3x+5y=10\\x+3y=1\\\\$

Second equation times 3:

$3x+9y=3$

1st equation minus equation above:

$-4y=7\\y=-7/4$

Insert to equation:

$3x+\frac{-35}{4}=10\\12x-35=40\\12x=75\\x=75/12=6.25$
