Let the dimensions be 10 cm by 12 cm by 9 cm and call them abc with their opposite angles being ABC:-
Using the cosine rule angle A = 54.64 degrees
Using the cosine rule angle B = 78.14 degrees
Angle C: 180 -54.64 -78.14 = 47.22 degrees
No right triangle can have any obtuse angles inside it.
As with any triangle, inside the triangle.
The 3 inside angles of any triangle add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
The 3 inside angles of a triangle add up to 180 degrees
A triangle has 3 sides and 3 inside angles that add up to 180 degrees. If you are asking about physical dimensions, a triangle is a two-dimensional shape.
-- In any triangle, the three inside angles always add up to 180 degrees. -- In an isosceles triangle, two of the three inside angles are equal.
All three angles inside an equilateral triangle are 60 degrees each.
No right triangle can have any obtuse angles inside it.
As with any triangle, inside the triangle.
The 3 inside angles of any triangle add up to 180 degrees.
inside the triangle ;) hope this helps!!
The 3 interior angles of any triangle add up to 180 degrees
The 3 inside angles of a triangle add up to 180 degrees
A triangle has 3 inside angles that add up to 180 degrees
Each triangle has 180 degrees on the inside angles.
The sum of the angles inside a triangle is 180 degrees.
