Answer:
Zx = 24 degrees
Step-by-step explanation:
since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).
Answer:
76
Step-by-step explanation:
When the vertex is at the origin and the directrix is at y = -2.5, the the parabola must be facing upwards and have a general formula of y = 4a x^2. In this case, a is equal to 2.5 that is, y = 4*2.5 x^2 equal to y = 10 x^2
55/8 and in the decimal form it's 6.875
