<mkb because of the isosceles triangle theorem. If two sides of a triangle are congruent, it is isosceles, so the angles opposite them are also congruent. 
Hope this helps!

Answer:

Step-by-step explanation:

Given that a line segment BK is an angle bisector of triangle ABC.  

When the line KM intersects BC such that BM=MK

we find an isosceles triangle BMK with two sides equal

Hence by isosceles triangles theorem, two angles opposite equal sides would be equal

i.e. m∠MBK≅m∠_BKM____

The isosceles triangle theorem states that  If two sides of a triangle are congruent, then angles opposite those sides are congruent.

If segment DF is an angle bisector, solve for x
klasskru [66]

Answer:

x = 19

Step-by-step explanation:

Since DF is an angle bisector then it divides the opposite sides into segments that are proportional to the other 2 sides, that is

\frac{DE}{DG} = \frac{EF}{GF} , substitute values

\frac{25}{22.5} = \frac{x-9}{9} ( cross- multiply )

22.5(x - 9) = 225 ( divide both sides by 22.5 )

x - 9 = 10 ( add 9 to both sides )

x = 19

A garden has 8 white roses and 11 red roses. One rose is plucked from the garden and then one more rose is plucked without repla
liberstina [14]
P(r/w) is the probability of picking a red rose at first picking and a white rose at second picking.
P(w/r) is the probability of picking a white rose at first picking and a red rose at second picking.

P(r/w) = \frac{11}{19}×\frac{8}{18} = \frac{88}{342}
P(w/r) = \frac{8}{19}×\frac{11}{18}=\frac{88}{342}

Notice that the second fraction is out of 18 because the second picking of rose will be out of 18 since the first rose is not replaced.

P(r/w) equals to P(w/r)
