Is a suplementary angle 180 degrees?

the angle and its supplementary angle added together is 180 the supplementary angle of angle y is 180-y


What is the opposite of a supplementary angle?

Y is a supplementary angle to angle X if X + Y = 180 degrees. The only opposite to X + Y = 180 is X + Y ≠ 180. Such an angle has no specific name.


How do you find angles of a triangle with a given slopes?

Slope = Rise/Run = y/x 1. leg = rise = y 2. leg = run = x 3. hypotenuse = √(x^2 + y^2) tan (angle 1) = x/y angle 1 = arctan(x/y) tan (angle 2) = y/x angle 2 = arctan(y/x)


How do you find the missing side of a triangle?

The most common way is to use Pythagoras' principle; "A2 + B2 = C2", where C is the side you are trying to find out and the other two are the lengths you already have. In this situation, C is the Hypotenuse, or the longest side of the triangle. When finding the shortest side, you have to rearrange the equation.However, this is only useful for Right Angled triangles. It is possible to change this to "A2 = B2 + C2 - (2BC)cos'a'", where A is the side you are looking for, and 'a' is the angle OPPOSITE this side. B and C remain the two given sides.Assuming you have a right triangle (one angle is 90o), we can use either the Pythagorean Theorem or the trigonometric functions.Let's assume your base is "x", height "y" and diagonal (hypotenuse) "r".Finding Values (Pythagorean Theorem):The Pythagorean Theorem states that, for a right triangle, r^2 = x^2 + y^2. We can use a little bit of algebra to find x, y and r.r = sqrt(x^2 + y^2)r^2 = x^2 + y^2r = sqrt(x^2 + y^2); remove the ^2 from rx = sqrt(r^2 - y^2)r^2 = x^2 + y^2r^2 - y^2 = x^2; move y^2 to the left side of the equationsqrt(r^2 - y^2) = x; remove the ^2 from xy = sqrt(r^2 - x^2)r^2 = x^2 + y^2r^2 - x^2 = y^2; move x^2 to the left side of the equationsqrt(r^2 - x^2) = y; remove the ^2 from yFinding Values (Trigonometric Functions):Acquiring Ratios:cos(angle) = x/rsin(angle) = y/rtan(angle) = y/xAcquiring Angles:cos-1(x/r) = anglesin-1(y/r) = angletan-1(y/x) = angleThat looks confusing. What are cos, sin, tan, etc?They're functions. You give a function input and it outputs something else. We won't worry about what they actually "are" - answering that requires calculus.x = cos(angle) * rcos(angle) = x/rcos(angle) * r = x; move r to the left side of the equationy = sin(angle) * rsin(angle) = y/rsin(angle) * r = y; move r to the left side of the equationx = 1 / (tan(angle)/y)tan(angle) = y/xtan(angle) / y = 1/x; move y to the left side of the equation1 / (tan(angle) / y) = x; flip the equationy = tan(angle) * xtan(angle) = y/xtan(angle) * x = y; move x to the left side of the equationr = 1 / (cos(angle)/x)cos(angle) = x/rcos(angle) / x = 1/r; move x to the left side of the equation1 / (cos(angle)/x) = r; flip the equationr = 1 / (sin(angle)/y)sin(angle) = y/rsin(angle) / y = 1/r; move y to the left side of the equation1 / (sin(angle)/y) = r; flip the equationI hope this helps,- Pritchard


What is the slope and y-intercept of y equals -2x plus 5?

y = -2x + 5 Slope is -2, that is the angle the line makes with the x-axis is such that tangent of that angle is -2 The y-intercept is 5
