I know that one is obtuse and acute
Answer:
72°
Step-by-step explanation:
So the three angles of a triangle always add up to 180°. This means that

This becomes:

And solves as:

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

The measure of the largest angle in the triangle is 72°.
Answer:
the first one
Step-by-step explanation:
x+5y>=5
isolate y then move on to y>=2x+4
