There are online drawing programs and there is the best, Geogebra!

yes. It is in AoPS. How can we submit images other than hand drawing?

Asymptote, that is a program that another forum uses isn't it?

can mathisfun use asymptote to draw pictures?

hi cooljackiec

At 5.44 the minute hand is pointing at exactly the 44 spot on the face.  So the angle between 00 minutes and 44 minutes will be 44/60 of 360 degrees ie. 6 degrees between each minute.

The hour hand will have moved somewhere between the 5 hour point and the 6 hour point.

That angle (5 - 6) is 5 x 6 = 30 degrees.  The hour hand is at 44/60 of that amount.  ie. 22 from the 5 point.  Put those two bits of information together and you will get the answer.

What is the number of degrees in the smaller angle formed by the hands of a clock at 5:44?

Hi;

3x + x = 180

4x = 180

x = 45° that is the acute angle.

3x = 3 * 45 = 135° is the obtuse angle.

just started at geometry.

Two lines intersect such that the measure of each obtuse angle formed by the lines is three times the measure of each acute angle formed by the lines. What is the measure, in degrees, of an obtuse angle formed by the lines?
