If it is a triangle then the 3rd angle is 70 degrees
It is an isosceles triangle and the 3rd angle is 72 degrees.
Using the ambiguous case rule in trigonometry the angles are 54.8 degrees and 97.2 degrees with a 3rd side of 18.0cm or 125.2 degrees and 26.8 degrees with a 3rd side of 8.17cm
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 degrees.
It is a right angle triangle because the 3rd angle has to be 90 degrees
The 3rd side of the right angle triangle can be found by using Pythagoras' theorem.
Using Pythagoras' theorem the 3rd side is 8 feet providing it is a right angle triangle.
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
Using the ambiguous rule in trigonometry its other angles are 35 degrees and 115.55 degrees with a 3rd side of 143.14cm or its other angles are 145 degrees and 5.55 degrees with a 3rd side of 15.35cm
If it is a triangle then the 3rd angle is 70 degrees
The 3rd angle is 30 degrees and so it is an obtuse or a scalene triangle with 3 different side lengths and no right angle.
It is an isosceles triangle and the 3rd angle is 72 degrees.
The longest side is twice as long as the shortest side.
If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side
Using the ambiguous case rule in trigonometry the angles are 54.8 degrees and 97.2 degrees with a 3rd side of 18.0cm or 125.2 degrees and 26.8 degrees with a 3rd side of 8.17cm
Use Pythagoras' theorem for a right angle triangle to find the length of the 3rd side.
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 degrees.
