Answer:
B grade
Step-by-step explanation:
75 + 90 + 88 + 86 = 339
339/4 = 84.75
Grade B = 80-89%
A)
Triangle ABX
Height = 8m
Base = 26-11 m
Find length by AB^2 = 15^2 + 8^2
b) Find AC by using AB as Height and BC as base
AC^2 = AB ^2 + BC ^2
K is centroid of the the triangle => The answer is 7.5
To find the surface area of a rectangular prism or cube, you would do height*width*2+height*length*2+length*width*2.
3/1200= 1/400=0.0025 chance of getting pulled, so unlikely
