This would be the arccos(21/25), which is 32.859880378889108736588042568 degrees! lol
An angle is formed by two rays that have the same endpoint. Tell why it makes sense that a straight angle forms a straight line.
An angle that forms a straight line has an angular measure of 180 degrees.
Because if it did not, it would not be called a straight angle!!
straight angle
A straight angle is 180o better known as a straight line. The hands of a clock showing a quarter past nine forms a straight angle.
180 degrees.An Straight angel has 180 degrees
False
It's not that easy to answer because a straight angle is like a straight line and I think that it would be on either every or none of the shapes that I would know of. Any shape has a right, obtuse,or acute angle. So, I am guessing that no shapes have straight angles. or that a straight angle is in every angle which is not true.
If you draw a straight line on a piece of paper and place a protractor over it you will see the reading is 180 degrees. In this sense a straight angle is 180 degrees.
A straight angle is 180 degrees, or twice the measure of a right angle. Therefore, it looks like a right angle that has been folded out into a flat line. Another way is to look at the arch of a 180 degree angle as a semicircle. Connect both ends of the semicircle and you have a straight line.
Supplementary angles forms a 180o angle (or a straight line). Complementary angles form a 90o angle.
yes, the entire molecule forms a straight line
