A tree broken over by storm forms a right triangle with the ground. If the broken part makes an angle 50o with the ground and if the top of the tree is now 20 ft from its base, how tall was the tree?
[tan(50)(20)] + [20/(cos(50)]=55ft
55 ft
A triangle with one angle over 90 degrees is an obtuse triangle.
A right angle triangle
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
scalene
30 degrees
Any triangle that has an angle measuring 90 degrees is a right triangle.
It is a right angle triangle and its 3rd angle is 70 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
A triangle with one angle over 90 degrees is an obtuse triangle.
45 degrees is an angle, not a triangle.A triangle containing an angle of 45 degrees can be any kind of triangle except an equilateral triangle.
It has 180 degrees, but one angle of the triangle has to be 90 degrees
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
The 3rd angle is 70 degrees which would form a right angle triangle.
It is a right angle triangle providing that the 3rd angle is 30 degrees.
