Simple equation:
☆Let's solve!

Answer:
Step-by-step explanation:
45=32+13
tan 45=tan(32+13)

or 1-tan 32 tan 13-tan 32-tan 13=0
Check the picture below.
now, an angle bisector I assume, since it intersects the opposite segment at D and then at E. An angle bisector cuts an angle in two equal halves, so if ∡CAB is 82°, that just means that ∡CAE is one of those halves, or 41°.
√x + 9 - 4 = 1
√x + 5 = 1
√x = -4
√x = √-4
x = 2i
P(Face card) =16/52 = 4/13
P(Spade) = 13/52 =1/4
P(Face ∪ Spade) = 4/13 + 1/4 = 29/52 = 0.557
