The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
The two angles are said to be supplementary angles if their sum is 180 degrees.
By the above property of angle, the equation is written as,
x + 100° + 3x = 180°
Simplify the equation, then we have
x + 100° + 3x = 180°
4x = 80°
x = 80° / 4
x = 20°
The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

Answer:
The triangle specified is not a right triangle.
Step-by-step explanation:
The angles of a right triangle will always add up to 180 degrees. The angles specified add up to 270 degrees.
There will also always be a 90 degree angle which makes up the right angle.
Since there will always be a 90 degree angle, the other angles will have to add up to 90.

Answer and explanation:
First, the domain is all real numbers except 0, since x = 0 is the asymptote.
D: x ∊ R, x ≠ 0
or
D: (-∞, 0) ∪ (0, ∞)
The range is everything below y = 0.
R: y < 0
or
R: (0, -∞)
Next, this function is never constant so there are only intervals of increasing and decreasing. The intervals meet at x = 0.

Answer:
A = picture attached
B = 51 in²
Step-by-step explanation:
The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.
Area of the triangle = 1/2 (base × height)
A = 1/2 (4 × 6) = 1/2 (24) = 12
The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.
Area of rectangle = length × width
A = 5 × 2.5 = 12.5
Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.
A = 6 × 2.5 = 15
Add the areas altogether to get the answer.
24 + 12.5 + 15 = 51.5 in²
