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.
A right angle is one whose measure is exactly 90Â°. On a drawing the symbol can be used to label two rays or segments as perpendicular (at right angles). In symbols we write that one line or segment is perpendicular to another using the symbol . An obtuse angle is one whose measure is strictly between 90Â° and 180Â°.
