Albedos of Various Earth Surfaces

An albedo is the amount of light reflected from a surface divided by the amount of light falling on the surface. The amount is typically measured in watts per square meter. The table shows the minimum and maximum albedos for different types of surfaces on Earth.

Solving quadratic equations using a graph is an effective method for locating estimated solutions or roots for quadratic equations or functions.
The real roots of a quadratic function might be zero, one (repeated), or two. Finding the origins involves solving a quadratic equation with the right-hand side equal to zero, such as ax² + bx + c = 0.
Points to consider to solve a quadratic equation using a graph :
• Rearrange the equation so that one side corresponds to the graphed function.
• Plot the function y= the other side of the equation.
• To find the solutions, draw vertical lines down to the x-axis from the intersection points.

Any triangle that has one 90-degree angle is said to have a right angle. Right triangles are those with an angle of 90 degrees, or "right angles," hence those with this angle. First, determine the third angle's measurement. You already know that C = 90 degrees because it is a right angle, and you are also aware of the size of A or B. Since a triangle's internal degree measurement must always equal 180 degrees, the third angle's measurement can be determined by applying the following formula: 180 – (90 + A) = B. The formula can also be turned around so that 180 - (90 + B) = A.
As an illustration, if you know that A is 40 degrees, then B is 180 – (90 – 40). It is easy to work out that B = 50 degrees if you simplify this to B = 180 - 130. Triangles can be resolved using the Law of Sines. Knowing the length of one side and the measurement of one other angle in addition to the right angle will especially assist you in finding the hypotenuse of a right triangle. The Law of Sines asserts that for any triangle with sides a, b, and c and angles a, b, and c, a / sin A = b / sin B = c / sin C.
Any triangle can be resolved using the Law of Sines, but only a right triangle will have a hypotenuse.
