It depends on the angle not all obtuse angles measure the same. To measure an angle you use a protractor.

Connect two ends of the obtuse angles, making a sort of M shape. Then use the line to connect the points at the top of the M. Pivoting the two obtuse angles might be necessary, depending on line length.

In an obtuse triangle, one angle is obtuse and the other two are acute. "The buildings are arranged in an obtuse triangle and occupy most of the long, thin parcel of land."

Unless you are an electrical engineer or a math teacher, every number you will ever use in a real world situation will be a real number.

Line up the vertex, then if it is an acute angle use the small number, obtuse use the big number, next all you have to do is bring your finger up to where the angle line is and see what number, big or small it lines up with on the protractor!

Right angles are used in architecture. All buildings are essentially based off of right angles (from the ground to a wall).

Whenever there are distances involved, as well as angles that are not precisely right angles.

I could use a protractor to measure the angles. You can also interpret whether the angle's acute,obtuse,or a right angle

I assume that the second use of the word "triangle" in the question should be angle. An obtuse triangle must have two acute angles.

we use angles in everyday life by surveying constuction ,msurgery , military and sports .

You can use straight angles to make sure countertops, or walls are straight and in a right formation.

The Arabic numbers, which is what are numbers are based on for the English language and are very similar to, use to have no curves or curved angles in them and had all acute, obtuse, or right angles. According to what number it was (for example 3) had three angles. Another example is 4, which still has four angles today.

There is an obtuse angle at either end of the bay window in our living room. A lot of the corners of the rooms of our house are not actually as square as they should be and are in fact slightly obtuse (eg 91o or 92o). At the top of some of our walls (at the join with the ceiling) there is a piece of caving which means the angle there is obtuse. To make full use of the land next to our house, our garage is shaped like a trapezium (the front is about 1m shorter than the back) so there is an obtuse angle between the front and one side of our garage. We have a floor standing lamp with an uplighting shade that makes an obtuse angle (with the upright pole). There are some obtuse angles in the mitring in the corners (of the covers) of the trunking I've put in. There are obtuse angles under the mantelpiece above our fireplace. The corner of one of the worktops in our kitchen has had the corner cut off, leaving two obtuse angles. Our staircase goes round a corner and the step that starts the corner has an obtuse angls . When any door is opened (unless it is at a right angle) it forms an obtuse angle (with either the doorway or the wall).

That triangle is not a acute, its an obtuse.
