What is 5 pi over 4 radians in degrees? <br> 45°<br> 135°<br> 225°<br> 315°
lidiya [134]
225 (since the fraction is over 180° (because 5Π/4 > Π we know that the answer must be bigger than 180° (because 180° = Π (radians)
and its less than 270° because 270° = 3Π/2 or 6π/4

Find m∠A.<br> A. 32<br> B. 26<br> C. 27<br> D. 30
krok68 [10]
<h3>Answer: B. 26</h3>

============================================

Use law of cosines to find angle A

a^2 = b^2 + c^2 - 2*b*c*cos(A)

9^2 = 6^2 + 14^2 - 2*6*14*cos(A)

81 = 36 + 196 - 168*cos(A)

81 = 232 - 168*cos(A)

81 - 232  = -168*cos(A)

-151  = -168*cos(A)

-168*cos(A) = -151

cos(A) = (-151)/(-168)

cos(A) = 0.8988095

A = arccos(0.8988095)

A = 25.9979801

A = 26 degrees approximately
