Answer:
x=60 degrees
Step-by-step explanation:
Since all of the sides are the same (we know that because of the dash marks on the sides) you take the number that all the angles of triangles added up equals which is 180 and divide by 3 which is 60
The answer is 3..y=mx+b where m is the slope
Answer:
or
Step-by-step explanation:
3x^2 + 5x - 12
To solve it, you need an equation, so I think you mean this equation.
3x^2 + 5x - 12 = 0
Using the quadratic formula, you have a = 3, b = 5, c = -12.
