x + (3x) + (x + 55) = 180
5x + 55 = 180
5x = 125
x = 25 . . . 3x = 75 . . . x+55 = 80
Check . . . 25 + 75 + 80 = 180 yay!
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
An angle that measures greater than 90 degrees but less than 180 degrees is an obtuse angle.
this is called an obtuse triangle the triangle that has one angle 90 degrees is called a right traingle a triangle that has 3 angles less than 90 degrees is called an acute triangle
obtuse angles
Greater than 90 degrees but less than 180 degrees.
obtuse angle
It is an acute angle which is greater than 0 but less than 90 degrees
180 degrees because the 4 interior angles of a quadrilateral add up to 360 degrees and the 3 interior angles of a triangle add up to 180 degrees
That's an impossibility because the 3 interior angles of any triangle add up to 180 degrees and the two given angles are greater than 180 degrees.
its a triangle * * * * * No, it an obtuse triangle is not a right angle triangle. An obtuse angled triangle has one angle which is greater than 90 degrees and the other two are acute. In a right angled triangle, the largest angle is 90 degrees while the other two are acute. So one cannot be the other.
if a triangle has a measure of 127 degrees, it's obtuse, meaning it has an angle that's greater than a right angle.
No because the sum of the 2 smaller sides of a triangle must be greater than its longest side in order to construct a triangle.
Classifying triangles is a great skill to know.Acute Triangles: These are triangles with measures lessthan 90 degrees.Obtuse Triangles: Any triangle with measures greater than 90 Degrees.Right Triangle: Any triangle with a Right Angle (exactly 90 degrees)
Not always, but it is possible. An obtuse triangle has 1 angle which measures greater than 90 degrees. A scalene triangle has all different lengths in size. It is possible for a triangle to have different angles, with one above 90 degrees, and have all different side lengths.
An obtuse triangle
A triangle that has an angle greater than 90o is an obtuse triangle.
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.
