Answer:
B
Step-by-step explanation:
Using the Sine Rule in ΔABC
=
=
∠C = 180° - (82 + 58)° = 180° - 140° = 40°
Completing values in the above formula gives
=
=
We require a pair of ratios which contain b and 3 known quantities, that is
=
OR
=
→ B
Answer:
Step-by-step explanation:
Hi there!
Slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two points that fall on the line are
and
On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:
Therefore, the slope of the line is 3. Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into :
I hope this helps!
