Cos math 21

WebIn the first quadrant, the values for sin, cos and tan are positive. Determine angle type: 21 is an acute angle since it is less than 90° cos(21) = 0.93358042664729 Write cos(21) in … WebWe just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms: cos(C) = a 2 + b 2 − c 2 2ab. cos(A) = b 2 + c 2 − a 2 2bc. cos(B) = c 2 + a 2 − b 2 2ca
