Answer:
because they can sense and understand the feeling of human whether they are happy or sad
The answer is C. 155
First find the measure of arc YZ.
The arc of WYZ is equal 180 degrees. So first add 25 to 85. Then subtract that to 180.
25+85=110
180-110=70.
Next add 70 to 85 since you want to find the measure of ZX.
70+85=155
So measure of ZX is equal to 155 degrees
A=Pe^(rt)
P = 800g
t = 8 years
A = 450g
r = This is what we will try and find to start with
450=800e^(r*8)
After running the math through a calculator, we end with r = -0.07192
Now we just re-input this information into our equation: A=800e^(-0.07192*16)
A=800e^(1.15072)
Now we will re-write the equation using the negative exponent rule:
A = 800 1/e^1.15072
Combine right side:
A = 800/e^1.15072
Then do the math:
A = 253.12709836......
That will give us A = 253 (rounded to the whole number)
I hope this helps! :)
Sector area= theta/360 x πr^2
Radius= 24/2= 12
Sector area= 120/360 x π(12)^2
Final answer :
Sector area = 48π
