Answer:
(2,1)
Step-by-step explanation:
Answer:
976cm^2
Step-by-step explanation:
Surface area:
Ara of cross section x 2 = 1/2 x 2 x 14 x 24 = 14 x 24 = 336
Area of base = 14 x 10 = 140
area of slope x 2 = 25 x 10 x 2 = 500
Total surface area = 500+140+336 = 640 + 336 = 973cm^2
ADC = 40 + 30 = 70 degrees
DBC is given at 45 deg
AEB = 100 degrees, vertical angle from intersecting lines
BCD = 50 + 50 = 100 degrees
The correct answer is letter A
