Answer:
Step-by-step explanation:
For the surface area we need to add up all the areas in the pyramid:
- area of the base
- area of the triangle sides (there are 4 triangles)
Area of the base:
the base is a square, and the area of a square is given by:
where is the length of the side:
, thus:
Area of the triangles:
one triangle has the area given by the formula:
where is the base of the triangle:
and is the height of the triangle:
, thus we have the following:
the expression that represents the surface area of the pyramid is:
substituting our values:
which is option B
Given the expression:
Let's simplify the expression.
To simplify the expression, we have:
Rewrite y⁸ = (y⁴)²
Thus, we have:
Answer:
The angle between the two sides of the right triangle is aproximately 31.003º.
Step-by-step explanation:
From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:
The angle between the two sides of the right triangle is aproximately 31.003º.
