Here are some academic vacobulary:
I hope this kinda helps you
You are given the lengths of the legs of the triangle.
The trig ratio that relates the lengths of the legs is the tangent.
tan x = opp/adj
tan x = 8/10
tan x = 0.8
Use the inverse tangent function to find x.
tan^(-1) 0.8 = 38.7 deg
x = 38.7 deg
First, multiply the length of the shaded region by the width.
Then, find the area of the non-shaded region.
Finally, subtract the non-shaded region from the shaded region.
We have tangent x=8/10
This simplifies to tangent x=0.8
Arctan=0.8, x=38.7 degrees.
Let me know if this helps :)

From the figure attached,
A parabola has been graphed.
Vertex of this parabola → (-1, -4) (lowest point)
Axis of symmetry → x = -1 (Parabola is symmetric about the vertical line x = -1 parallel to the y-axis)
x- intercepts (points of intersection of the parabola and x-axis) → (-1, 0) and (1, 0)
y- intercepts (point of intersection of the parabola and y-axis) → (0, -3)
Concavity of the parabola → Concave UP
Given: Miguel is staining a wooden box. To determine how much stain he needs, he'll need to find the surface area of the box.
It is True or False question.
The wooden box is a three-dimensional figure.
It may be a cube or rectangular prism. Both has six faces.
So Miguel need to staining the six faces.
To find the stain that needed, he has to find the surface area of the box.
Surface is nothing the sum of the areas of the six faces.
Surface area of a rectangular box = 2(L*W + W*H+ H*L), where "L is the length , W is the width and H is the height.
Surface area of a cube = 6*a^2 (Where "a" is the side of a face, in a cube all the sides are in the same measure)
So, the answer is True.
