Answer:
a
Step-by-step explanation:
math
M of A = x
m of B = 2x-7
m of C = 2x+2
By the angle sum property of a triangle, we know that all the angles of a triangle add up to 180 degrees.
Thus we can create a linear equation
x + 2x-7 + 2x+2 = 180
4x = 185
x = 185/4
x = 46.25
Thus
m of A = 46.25
m of B = 2(46.25) -7 = 85.5
m of C = 2(46.25) +2 = 90.5
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.
I believe it would be 3 but dont take my word
The same value as cosα
cosα=sin(90-α) and vice versa
sinα=cos(90-α)
