Answer:
x+y=0 and 3x-2y=10
Step-by-step explanation
Let the numbers be x and y.
The sum of the two numbers is 0

Letting the smaller number be y and the
larger number be x:
twice the smaller number

Also, 3 times the larger number

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

Therefore the equations are

and

The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
180- 124= 56
So 56 degrees
