So, this problem asks us to construct an equation that relates the amount of money left to the amount of weeks that has gone by. First, let's assign variables. Let y be the amount of money left, while x is the number of weeks she receives money. The equation would be:
<em>y = 250 - 10x</em>
That figure obviously doesn't go with this problem. It doesn't matter; this is triangle ABC labeled the usual way.
c = 10, B = 35°, C = 65°
We have two angles and a side. The third angle is obviously
A = 180° - 35°- 65° = 80°
The remaining sides are given by the Law of Sines,
Answer: A=80°, a=10.9, b=6.3, third choice
Answer:
1 out of 15
Step-by-step explanation:
Conic sections are defined using a directrix (<span>a fixed line used in describing a curve or surface) and a focus, and those are: parabola, ellipse, and hyperbola. </span>
