Answer:
Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve.
Eliminate y's
multiply 2nd equation by 3 and add to first
5x+3y=55
<u>12x-3y=30 +</u>
17x+0y=85
17x=85
divide both sides by 17
x=5
sub back
4x-y=10
4(5)-y=10
20-y=10
-y=-10
y=10
x=5
y=10
(5,10)
or you could subsitution with y=4x-10
(5,10)
