8. A, B, A + 2B, A + 4B are the angles between
0 and 90. Also, sin (A + 2B) =√3\2and
COS (A + 4B) = 0; A > B, then find A and B.

Answer:
A=30, B= 15
Step-by-step explanation:
sin(a+2b)=√3/2
sin(a+2b)=sin60
a+2b=60
a=60-2b
cos(a+4b)=0
cos(a+4b)= cos90
a+4b=90
a=90-4b
60-2b=90-4b
4b-2b=90-60
2b=30
b= 15
a+2b=60
a+2(15) =60
a+30=60
a=60-30
a=30
