Answer:
Angle B is 44 degrees.
This is a right triangle.
Steps:
The sum of interior angles in a triangle equals 180 degrees. The given triangle is a right triangle.
So A + B + C = 180
We are given A and C.
46 + B + 90 = 180
B + 136 = 180
180 - 136 = 44
Answer: A three-sided polygon is a triangle.
There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Isosceles – has two equal sides, with the third one a different length.
Step-by-step explanation:
Dy/dt = dy/dx * dx/dt
dy/dx = 6x^2 - 4
when x = 1, dy/dx = 6 - 4 = 2
dy/dt = 2 * 4 = 8.
Slope of the vertical line: undefined
Equation of the vertical line: x=5
f(x)+g(x) = 3x^2-x-4
f(x)-g(x) = 4x^2-7x-4
Foil (2x-6)(5x+1) = 10x^2-28x-6
The roots (zeros) of the parabola are -2 and 3
X-coord for vertex = -1/2
Last problem: s^2 + 4s
