Well, the sum of the angles in a triangle equals 180 degrees.
So you do 180 minus the two angles to get the third angle.
180 - 78.4 - 57.2 = 44.4
44.4 degrees

To find AC, use the law of sines.
Length A / sin (angle a) = length b / sin(angle b)

Use the fundamental identities to verify
Vilka [71]

Answer:

see below

Step-by-step explanation:

6 cot ^2 (y) ( sec^2 (y) -1) = 6

We know that ( sec^2 (y) -1) = tan ^2(y)

6 cot ^2 (y) tan ^2 (y) = 6

We know cot = cos/ sin   and tan = sin / cos

6 cos/ sin ^2 (y) sin/cos ^2 (y) = 6

6 ( 1) = 6

6=6
