Answer:
.
Step-by-step explanation:
Since we are in quadrant two, cosine value is negative while sine value is positive.
We are going to use the Pythagorean Identity:
.






Since cosine and secant are reciprocals then they will have the same sign as along as they both exist.

I don't see this answer as I'm going to rationalize the denominator.

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.
Volume and Capacity or Mass
I'm guessing you needed this factored and apologies for the lateness, this popped up after I answered another question.
12m³ - 22m² - 70m
2m(6m² - 11m - 35)
2m(6m² + 10m - 21m - 35)
2m(2m(3m + 5) - 7(3m + 5))
Your factored answer is:
2m(2m - 7)(3m + 5)
