Explanation:
The given equation is False, so cannot be proven to be true.
__
Perhaps you want to prove ...
This is one way to show it:
__
We have used the identities ...
csc = 1/sin
cot = cos/sin
csc^2 -1 = cot^2
tan = sin/cos
Answer:
- A. (x + 16) + (6x − 4) = 180
Step-by-step explanation:
Inscribed quadrilateral has opposite angles supplementary.
<u>So</u>
or
<u>Since</u>
- m∠A = x + 16,
- m∠B = x,
- m∠C = 6x - 4,
- m∠D = 2x + 16
we can use either pair of angle measures to work out the value of x and then find the value of each angle.
<u>We can verify the first option is the only correct one.</u>
- m∠A + m∠C = 180°
- (x + 16) + (6x − 4) = 180
X=-3. The question is wanting to know that if y=3, what does x equal? Well the only y-value that has y=3 on this line is x=-3
You have to find the areas of the triangle faces and rectangular faces, so…
the triangles' areas are:
6 • 16 = 96
the rectangles on the sides have areas of:
10 • 9 • 2 = 180
and the base rectangle has an area of
16 • 9 = 144
the surface area is 96+180+144 which is 420 in2.
The order of operations is:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
So division comes first:
Now subtraction:
