Answer:
<ECF = 45 degrees
Step-by-step explanation:
If ABCD is a square, then the diagonal AC divides angle <C and angle <A in two equal parts. Angles A and C are also 90 degrees each due to the act that the figure is a square. Therefore their bisection would render 90/2 = 45 degrees.
Notice as well that angle <ECF is opposite by the vertex to one of these 45 degree angles, and then it must measure the same amount (45 degrees).
So, <ECF = 45 degrees
87.4 would be rounded to 87.
9.6 would be rounded to 10.

Answer:
elephant: 566.5 kilograms, Bengal tiger: 224.4kilograms, lion: 193.8 kilograms, , giraffe: 164.8 kilograms, giant panda: 122.4 kilograms
Step-by-step explanation:
elephant: 566.5 kilograms, giraffe: 164.8 kilograms, lion: 193.8 kilograms, Bengal tiger: 224.4kilograms, giant panda: 122.4 kilograms
A=p (1+I/k)^tk
26000=p (1+0.12/2)^(2×8)
Solve for p
P=26,000÷(1+0.12÷2)^(2×8)
P=10,234.80
