Answer:
c
Step-by-step explanation:
because the real awnser is 57/4 but simpfly
Answer:
C
Step-by-step explanation:
because you have to foil then do -b/2a
Answer:
b is the angle being measured while a is the angle at a point with b
Step-by-step explanation:
The only time we use 360 for calculating an angle is when the two angles are at a point as both of them assuming a and b sum up to 360°.
Therefore a + b = 360
and if b is being measured, b = 360 -a
Answer:
B
Step-by-step explanation:
recall that any radical expression
has real solutions only if A is not negative. (otherwise you will have imaginary solutions)
hence in this case we have
,
for real solutions, 8x must be ≥ 0,
since 8 is a positive number, x must be ≥ 0 (answer)
