Questions & Answers. Our Samsung refrigerator started flashing at 34 degrees and would not cool. I disassembled the panel inside the refrigerator and found severe ice build up covering the evaporating core. I also noticed that the cooling fan was working fine. So I used a hair dryer to remove the ice build up and the fridge worked fine for 2 days.
WXYZ is a kite. If the measure of angle WXY is 120Â°, the measure of angle WZY is 4xÂ° and the measure of angle ZWX is 10xÂ°, find the measure of angle ZYX. In accordance with the properties of a kite (rhombus), angle ZYX is equal to angle ZWX. And, the sum of the angles of a quadrilateral is 360. So let's make the equation for the sum of the angles: 120 + 4x + 2(10x) = 360.
Measure, calculate, and draw in the refracted ray with the calculated angle of refraction. In each of these two example problems, the angle of refraction is the variable to be determined. The indices of refraction (n i and n r) are given and the angle of incidence can be measured.r = index of refraction of the refractive medium. This relationship between the angles of incidence and refraction and the indices of refraction of the two media is known as Snell's Law. Snell's law applies to the refraction of light in any situation, regardless of what the two media are.
