The angle of contact is greater than 90° in
WebAn acute angle is an angle whose measure is less than 90∘. That is, in a pair of intersecting non-perpendicular lines, the smaller of the angles are acute. A right angle is an angle whose measure is equal to 90∘. That is the measure of the angles of perpendicular lines. An obtuse angle is an angle whose measure is greater than 90∘.

WebTHE large values given by Fogg 1 for the contact angles of water with leaves suggest that these are apparent rather than true contact angles. Adam 2 and Wenzel 3 have shown that rough surfaces give an apparent contact angle which is greater than the true contact angle for the smooth material of the surface when the true contact angle is greater than 90°. WebDec 4, 2024 · 973. IF you are only using the "trig functions" on right triangles then there is no reason to use angles greater than 90 degrees. But generalizations of the trig functions (sometimes renamed "circular functions") are very useful as "periodic functions" modeling repetitive phenomena. As functions, we want them defined for all real numbers.
