A^2 = b^2 + c^2 - 2bc cos a
= 11^2 + 5^2 - 2*5*11 cos 40
= 7.86 to 2 DP's
to find the remaining angles use the sine rule:-
a / sin A = b / sin B so
7.857/ sin 40 = 11 / sin B
sin B = 11 sin40 / 7.857 = 0.8999
<B = 64 degrees
so <C = 180 - 64-40 = 76 degrees
Answer:
Wendy needs to run 3 laps to run 3 miles.
Hope this helps. :)
C. 6.2g can be combined with -3/8y. This is because they both end in ‘y’.
61 because it occurs the most
Hope that helped:)!!!!!!!
c.y+3=f(x) and 0+3 therefore x=3
