Obtuse: b^2 + c^2 > a^2
Right: b^2 + c^2 = a^2
Acute: b^2 + c^2 < a^2
A^2 + B^2 + c^2 - 2bc*cosA
As (A), is an Obtuse cos A is Negative say 2bccosA = - k then;
a^2 = b^2 + c^2 + k
a^2 > b^2 + c^2
So, your Answer would be (B)
Hope this helps!!.!
Answer:
The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).
Answer:
4 months
Step-by-step explanation:
(2000 *6)/100 = 120
120x = 480
X = 480/120
X = 4 months
This should be recognized as the difference of perfect squares which is of the form:
(a^2-b^2) and the difference of squares always factors to:
(a-b)(a+b) in this case:
(3x-8)(3x+8)
Answer:
39.9
Step-by-step explanation:
a/sinA = c/sinC
a/sin(77) = 16/sin(23)
a = sin(77) × 16/sin(23)
a = 39.89935764
