The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
Use a protractor.
It depends on the angle not all obtuse angles measure the same. To measure an angle you use a protractor.

We would typically use a sextant to measure the angle of a star above the horizon.

If you absolutely needed to measure an angle to find out its degree measure, you would use a protractor.

put the protractor on the vertex and look up at the degree's and look belowacute angle =has a measure between 0 degree's and 90 degree'sright angle =has a measure of 90 degree'sobtuse angle = has a measure between 90 degree's and 180 degree'sstraight angle = has a measure of 180 degree'sthat's how you use a protractor to measure angles.
There are special angle-measuring instruments which you can use to measure the angle.
