Step-by-step explanation:
a2 +b2=c2
=
According to trignometery
If we take AB base and AC perpendicular
Then we can apply
Cos(45) = AC / 11
0.7071 = AC/11
0.7071 × 11 = AC
AC = 7.78
2nd Option is Correct
Hope this helps :)
Answer: 3:45PM
Step-by-step explanation: 245 / 35 = 7. 7 hours after 8:45AM is 3:45PM.
Ax^2+bx+c=0
a=2
b=-1
c=-3
b+-sqrt( b^2 - 4ac)
2a
so...
-1 +- sqrt(1 + 24)
4
-1 +- 5
4
x= -1 + 5 = 1
4
or
x= -1 - 5 = -3/2
