Yes. Since the sum is 180 degrees, that set of three numbers
is a perfectly good set of angles for a triangle.
Nope - because the internal angles of a triangle must total 180 degrees !
No. The interior angles of a triangle must add up to 180° 150° + 10° + 10° = 170° ≠ 180° Therefore a triangle cannot have interior angles of 150°, 10° and 10°
8 because there are 180 degrees in a triangle and 8*180 = 1440 degrees The interior angles of a 10 sided shape add up to 1440 degrees
This is the sequence of triangular numbers. You draw one dot. Then you draw two dots in the line below - one to the left and one to the right of the first dot. You now have a triangle, of three dots. Then you draw three dots in the next line and you get a triangle with 6 dots. Next, four more dots in the next line giving a triangle with 10 dots. The name is easy to understand if you can visualise or even actually draw these dots. It is difficult to demonstrate through an ordinary word processing package.

No. The interior angles of a triangle must add up to 180° 150° + 10° + 10° = 170° ≠ 180° Therefore a triangle cannot have interior angles of 150°, 10° and 10°
You could draw two arcs from the North pole to the equator, with a 10 degree separation. The two arcs and the equator would form a 190 degree spherical triangle.
No. For example, say the two angles are 10° and 20°. Then the other angle is 180°-10°-20°=150° and that is not a right angle. But if the triangle has two equal acute angles of 45 degrees then the 3rd angle must be 90 degrees which will form a right angle triangle.
It is pi/10 radians ( = 36 degrees).
No.
The area of a triangle is (1/2) x (length of the base) x (height of the triangle). You ought to be able to handle it from this point.
A regular 12 sided polygon each interior angle measures 150 degrees
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
Well, darling, the sum of the angles in a triangle is always 180 degrees. So, if you add 98 and 10 together, you get 108. Subtract that from 180, and voila, you've got yourself the measure of the third angle: 72 degrees. Math doesn't have to be a drama, honey!
No, it cannot.
On the clock each minute represents 6 degrees and so 10 minutes is 60 degrees and 25 minutes is 150 degrees
