Answer:
x=25 degrees
Step-by-step explanation:
x= 90 degrees - given(65 degrees)
x=90-65
x=25 degrees.
The angles add up to 90 degrees.
Answer:
Hexagonal pyramid DOES NOT have any rectangular faces
Step-by-step explanation:
Given some solids we have to choose that one which DOES NOT have any rectangular faces
Pentagonal prism has total 7 faces out of which two faces are pentagons and 5 are rectangular.
Hexagonal pyramid is a pyramid with a hexagonal base upon which are erected 6 isosceles triangular faces.
It has no rectangular face.
Rectangular prism is a solid with 6 rectangular faces also known as cuboid.
Square pyramid is a pyramid with 1 square base. As every square is a rectangle.
we can say 1 rectangular face.
Hence, Hexagonal pyramid DOES NOT have any rectangular faces.
Option B is correct.
Divide 138.16 by 3.14. This gives a diameter of 44 meters.
Hope this helped :)
Hello from MrBillDoesMath!
Answer:
Choice E and F
Discussion:
From the quadratic formula with a = 3, b = -1, and c = 6
x = ( -b +\- sqrt(b^2 - 4ac) ) / (2a) => substitute in a,b,c from above
x = ( -(-1) +\- sqrt((-1)^2 - 4(3)(6)) / (2*3) => discriminant = 1 - 72 = -71)
x = ( 1 +\- sqrt(-71))/ 6
which are choices E and F
Thank you,
