Answer:
Step-by-step explanation:
the relationship is known for a and b is adjacent.
Answer:
A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
Step-by-step explanation:
x = 3 + t
y = t² − 4
Eliminating the parameter:
t = x − 3
y = (x − 3)² − 4
This is an upwards parabola with a vertex at (3, -4).
x = 3 + t, so as t increases, x increases.
So the curve is traced from left to right.
X = 32.
117 + 31 = 148.
180 - 148 = 32. (All angles in a triangle add up to 180 degrees)
