Step-by-step explanation:
according to the property of the parallelogram m(OPE)=m(OHE), then 2x+25=3x-15, then (after calculation the 'x'):
1. x=40;
2. m(OHE)=2*40+25=105°;
3. m(OPE)=3x-15=3*40-15=105°;
4. m(HOP)=180-m(OPE)=180-105=75°;
5. m(HEP)=m(HOP)=75°.
Answer:
maximum value is 17.
Step-by-step explanation:
8.5=1/2(x-0)
8.5=1/2x
8.5=x/2
8.5×2=x
17=x
x=17

Step-by-step explanation:
Answer: 5 inches
Step-by-step explanation:
V = S * (30-2S)^2
V = S(900-120s+4s^2)
Volume = 4s^3 -120s^2 +900s
Find local maximum from graph at 5 (or take derivative = 0)
The answer is it is a circle. hope that helps ;)
