obtuce angle
An acute angle is any angle that is between 0° and 90°.At the exact hour mark, the minute hand is always at the 12.And so, the hours where the clock form an acute angle are:1 o'clock2 o'clock10 o'clock11 o'clockThus, there are 4 hours.

obtuse
On a standard wall clock, 4:00 is an obtuse angle.
The correct answer is 120 DEGREES
About 5 after 4.
4 times 6:00am, 6:00pm, 12:30am,12:30pm
120 degrees and 240 degrees.
120 degrees is the angle made by the hands of a clock at 4 o clock. To get this answer, you could divide the clock into equal parts (12), and find the ratio of the time in terms of parts to the total number of parts of the clock (which would be 4/12 in this case). Then, you cross multiply the ratio you got, to the ratio of the unknown degrees to the total number of degrees in a circle (x/360). (4 * 360 = 12x). The answer should be 120 degrees.
The hands on a clock must be greater than 90 degrees to be obtuse, so you find times where the time is >90 degrees.Examples are: 4:00, 5:00, 6:00, 7:00, 8:00.
Let's call the two angles angle 1 and angle 2. We are given that angle 1 and angle 4 form a linear angle and that angle 2 and angle 4 form a linear angle. Because linear angles measure 180 degrees, we arrive at: m<1 + m<4 = 180 m<2 + m<4 = 180. By subtracting the second equation from the first, we get: m<1 - m<2 = 0. And finally: m<1 = m<2. Thus, angle 1 is congruent to angle 2.
