Answer:

ABE is 75

Step-by-step explanation:

If ABD = 108, that is the entire picture.

CBD is the part that is bisected. Bisector line BE cuts the angle in half.

Since CBD is 66, half of it is what is pictured on both sides of line BE.

Half of 66 is 33.

Angles EBE and EBD are both 33.

Angle ABE is ABC + CBE.

Angle ABE is also ABD - EBD.

ABE = ABD - EBD

ABE = 108 - 33

ABE = 75

Rzqust [24]

Answer:

There are 70 sheep in the farm.

Step-by-step explanation:

Consider the provided information.

Let c represents the cows, s represents the sheep and p represents the pigs.

The number of cows and the number of sheep are in the ratio 6:5.

$\dfrac{c}{s} =\dfrac{6}{5}$

$c =\dfrac{6s}{5}$

The number of sheep and the number of pigs are in the ratio 2:1.

$\dfrac{s}{p} =\dfrac{2}{1}$

$p =\dfrac{s}{2}$

The total number is 189.

$c+s+p=189$

Substitute the value of c and p in above.

$\dfrac{6s}{5}+s+\dfrac{s}{2}=189$

$\dfrac{12s+10s+5s}{10}=189$

$27s=1890$

$s=70$

Hence, there are 70 sheep in the farm.
