B=h+4, m=h-2 now we are told
b+h+m=11, using b and m found above in this equation gives us:
h+4+h+h-2=11
3h+2=11
3h=9
h=3 and since b=h+4, m=h-2
historical=3, biography=7, mystery=1
Answer:
x=30o+n90on∈Z
Step-by-step explanation:
cos2x=sin(90o−2x)=sin(2x−30o)
Which mean 90o−2x=2x−30o+n360o
or 90o−2x+2x−30o=(2n+1)180o
The later cannot be true.
so x=30o+n90on∈Z
Answer:
12 meters
Step-by-step explanation:
Area = length × width. If we divided 96 (area) by 8 (width) we should get the length. 98 ÷ 8 = 12.
