Answer: angle B = 47 degrees</h3>
========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number
Make sure your calculator is in degree mode.
arccos is the same as inverse cosine often labeled on calculators.

Answer C
Answer:
<em>945 minutes.</em>
Step-by-step explanation:
<em>10% = 0,1</em>
<em>450 + 450 · 0,1 = 495 (minutes) - Oliver will read next month.</em>
<em>450 + 495 = 945 (minutes) - he read in all during the two months.</em>
