Answer: m∠E = 60°
Step-by-step explanation:
Here, ABC and DEF are two triangles in which,
m∠A = 90°, m∠B = 60° and m∠C = 30°
Also, Δ ABC ≅ Δ DEF
Thus, By CPCTC ( congruent part of congruent triangles are congruent )
m∠A = m∠D = 90°
m∠B = m∠E = 60°
m∠C = m∠F = 30°
Hence, the measurement of angle E is 60 degree.

Step-by-step explanation:
Here is the complete question: Find the rate of change for the situation:
A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.
Given: 1st situation, A chef cook 9 lbs chicken for 36 people.
2nd situation, chef cook 17 lbs chicken for 68 people.
∴ 1st situation, weight of chicken per person=
Weight of chicken per person=
2nd situation, weight of chicken per person=
Weight of chicken per person=
In both the situation chef cook same amount of chicken per person, which is
∴ Rate of change is
