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:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°
B 1 since you would round 1.9 to 2 and 0.7 to 1
You can use the formula to solve for the y-values in the table. Insert the x-value into the equation: y = 2x - 2
(ex. y = 2(1)-2)
So..
x | y
0 | -2
1 | 0
3 | 4
5 | 8
8 | 14
10 | 18

Answer:
Step-by-step explanation:
now the equation looks like
3-4Cos(x)=y
hmmm i'm wondering if you can figure it out from here??? it's the same as the other two.. plug in that 
/2 .. can you? :)
