As many as you like because any triangle that has a 90 degree angle is always a right angle triangle.

How many triangles exist with the given angle measures 30 65 85?

As many as you like but they will all be scalene triangles formed by the given angles that add up to 180 degrees


How many triangles exist with the given angle measures 30 and deg 65 and deg 85 and deg?

As many as you like but they will all be scalene triangles from the given interior angles that add up to 180 degrees.


How many triangles exist with the given angle measures 55 degrees 45 degrees 90 degrees?

No triangle exists with the given angle measures. None because the given angles add up to 190 degrees and the 3 angles in any triangle add up to 180 degrees.


How many triangles exist with the angle measurements 40 25 115?

40° + 25° + 115° = 180°, which is the correct total for the angles (in degrees) of a triangle. There are infinitely many triangles with those angles.


How do you measure a hypotenuse angle if you know the other two angles?

The hypotenuse is a side, not an angle. However, if you mean the angle across from the hypotenuse, it is always 90 degrees, or pi/2 radians because hypotenuses only exist in right triangles.


What is an angle that is 361 degrees or more called?

Doesnt exist!


What do you call an angle that is bigger than 360 degrees?

Doesn't exist. No such thing.


How many triangles exist with these measures 4 m 4 m 7 m?

Infinitely many could, but they would all be congruent to one another.


What is the area of a triangle if angle a equals 42 degrees angle b equals 87 degrees and angle c equals 24 degrees?

A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.


Angle greater than 90?

An angle greater than 90 degrees would be considered an "obtuse" angle. Once you get to 180 they are considered "Straight" lines. Once you pass 180 degrees they are called "Reflex" angles.


Do 2 perpendicular lines make a straight angle?

Two perpendicular lines will meet in a right angle (90 degrees) if they exist on a flat plane.


Incenters on triangles?

Do exist.
