Answer:
A 20 sqrt(2)
Step-by-step explanation:
4 sqrt(50) + 4 sqrt(12) - 2 sqrt(27) minus 2 sqrt(3)
We know that sqrt(a) sqrt(b) = sqrt(ab)
this is the first expression
4 sqrt(25)sqrt(2) + 4 sqrt(4)sqrt(3) - 2 sqrt(9)sqrt(3)
4*5sqrt(2) + 4*2 sqrt(3) - 2*3 sqrt(3)
20 sqrt(2) +8 sqrt(3)-6sqrt(3)
20 sqrt(2) +2 sqrt(3)
Now we subtract 2 sqrt(3) from the above expression
20 sqrt(2) +2 sqrt(3) - 2 sqrt(3)
20 sqrt(2)
Distribute the
And combine the s terms and you should be able to solve it
Answer:
m∠BOC = 53°
Step-by-step explanation:
The definition of an angle bisector is that it divides an angle into two congruent angles. ∠AOC is divided by angle bisector OB into angles ∠AOB and ∠BOC, hence those two angles are congruent.
m∠AOB = m∠BOC = 53°
