C because it has an equal number of y's on each side so to solve it you would subtract 4y from both sides leaving:
5 = -6
which is not possible so there is no solutions.
The answer is B because the base of the triangle is a square as said then three triangles meet up at the point and make a pyramid
W=IH/V that is the final answer
The sum of interior angles in a regular octagon equals 1080 degrees.
So 1080 / 8 = 135
z = 135
Answer:
A = 54cm^2
Step-by-step explanation:
A = (base × height)/2
base = 9cm
height= 12cm
A = (9 × 12)/2
A = 108/2
A = 54
