Answer:

Of the 600 elephants that he observes in random places in the reserve, he counts \frac{8}{30}(600)=160 elephants with broken tusks.

Step-by-step explanation:

Let x denotes number of elephants having broken tusks out of 600 elephants.

Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.

So,

Of the 1 elephants that he observes in random places in the reserve, he counts \frac{8}{30} elephants with broken tusks.

Therefore,

Of the 600 elephants that he observes in random places in the reserve, he counts \frac{8}{30}(600)=160 elephants with broken tusks.

AB is parallel to CD.
kogti [31]

Answer:

Step-by-step explanation:

∠ABC = ∠BCD    { AB // CD; BC TRAVERSAL, alternate angles are equal}

∠ABC = 20

∠BCA = ∠BAC     {angles opposite to equal sides are equal}

∠BCA = ∠BAC = x

x + x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80
