Answer:
x = 25
Step-by-step explanation:
We know that the remaining angles add up to 90°, because the right angle (triangles have 180° total.)
2x + 15 + x = 90 | Given
3x + 15 = 90 | Combine x
3x = 75 | Subtract 15
x = 25
Answer:
A) y = -2x
B) y = x - 3
Step-by-step explanation:
A) you need to have a negative 'x' coefficient and no y-intercept
B) you need to have a positive 'x' coefficient and a negative y-intercept
No, but 16/15 is equivalent
