Answer:
A
Step-by-step explanation:
Sin (Angle) = Opposite / Hypotenuse
Sin (X) = 8/17
X = Arcsin(8/17)
X = 28.07 degrees.
Answer:
b
Step-by-step explanation:
so 0.5x is a slope of 1/2, which is rise 1 | run 2, and b matches that!
Answer:
2 real solutions
Step-by-step explanation:
Get all the terms to one side
10n^2 = 10 - 8n
10n^2 +8n -10 =0
ax^2 +bx+c =0
The discriminant is
b^2 -4ac
8^2 - 4(10)(-10)
64 +400
464
If the discriminant is greater than 0 we have 2 real solutions
