Needing help, the secretary of the united states department of agriculture asked your teacher, "if a chicken-and-a-half can lay
Flura [38]

we are given that

3 chickens to lay 32 eggs

now, we can find number of eggs per chicken

number of eggs per chicken= (total eggs)/(total chicken)

so, we get

number of eggs per chicken is

=\frac{32}{3}

now, we can set up following

1.5 chicken : 1.5 eggs : 1.5 days  

3 chickens : 3 eggs : 1.5 days  

1 chicken : 1 egg : 1.5 days

Since, changing number of chicken won't affect time

time to lay eggs will always remain same

so,

for 1 chicken to lay =\frac{32}{3} eggs

it takes

=\frac{32}{3}*1.5 days

=16 days..............Answer

We know that the sum of measures of internal angles in each quadrangle is 360°.

Look at the picture.

\alpha+\beta+\gamma+\delta=360^o\ \text{and}\ \delta+\tau=360^o\\\\\text{therefore}\\\\\alpha+\beta+\gamma+\delta=\delta+\tau\ \ \ |-\delta\\\\\alpha+\beta+\gamma=\tau

Therefore we have:

\theta=35^o+83^o+23^o=141^o

Answer: θ = 141 deg.
