right angle!
By using trigonometry
To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.
A right triangle has a 90 degree angle in it. This is not to be confused with a wrong triangle, which has two 90 degree angles.
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
It has a 90 degree angle..
in triangle def side de equals 5 and angle d equals 55 find fe
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
67 degrees
right angle!
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
The answer rounded to the nearest tenth is 25 meters.
By using trigonometry
The 110 degree angle makes this triangle an obtuse triangle.
Because it's a right angle triangle use any of the trigonometrical ratios to find the two interior acute angles: tangent = opp/adj, sine = opp/hyp and cosine = adj/hyp The angles are to the nearest degree 46 and 44
