It is either A or B. I'm not sure which one.
Step-by-step explanation:
step 1. very tough question! you need the slant height (h)
step 2. h = sqr(8^2 + 3^2) = sqr(73) sqr is the square root
step 3. SA = B + ph/2 where SA is the surface area, B is the base area, and p = the lateral perimeter
step 4. we will call the hypotenuse of the right triangle c
step 5. c = sqr(13^2 + 6^2) = sqr(205)
step 6. SA = (1/2)13(6) + (13 + 6 + sqr(205))sqr(73)/2
step 7. SA = 39+ (33.3178)(8.5440)/2 = 181.3336 cm^2.
Answer:
Step-by-step explanation:
The slope of line u is 9/2; the line perpendicular to that is the opposite reciprocal...opposite sign and the flip of the fraction. The perpendicular slope is -2/9
