Let the sides be abc and their opposite angles be ABC:-
Using the cosine rule angle A: (7^2 +6^2 - 8^2)/(2*7*6) = 75.5 degrees
Using the sine rule angle B: (7*sin75.5)/8 = 57.9 degrees
Angle C: 180 -75.5 -57.9 = 46.6 degrees

What is different about similar and congruent figures?
Congruent figures are identical in dimensions and angles whereas similar figures have dimensions in proportion to congruent figures but both have exactly the same angles.
What is different about similar figure and congruent figures?
Congruent figures are identical in dimensions and angles whereas similar figures have dimensions in proportion to congruent figures but both have exactly the same angles.
Can a triangle have two parallel angles?
In two dimensions, lines can be parallel, angles cannot. So no plane shape has parallel angles.
How do you calculate the angles of a right triangle with coordinates?
With a protractor or use trigonometry if you know its dimensions
What are the angles of a right triangle 2ft by 3.5in by 24.5ft?
The figures given in the question cannot be a triangle, leave alone a right angled triangle.

How many dimensions triangle have?
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.
Can a triangle have two parallel angles?
In two dimensions, lines can be parallel, angles cannot. So no plane shape has parallel angles.

What is the area of an isosceles triangle that has two equal sides of 8.75 cm and two equal angles of 63 degrees showing work and final answer to 3 significant figures?
Area: 0.5*8.75*8.75*sin(54 degrees) = 31.0 square cm to 3 significant figures
What are the angles of a right triangle 2ft by 3.5in by 24.5ft?
The figures given in the question cannot be a triangle, leave alone a right angled triangle.
Which figures have at least one pair of congruent angles?
A square, a rectangle, an equilateral triangle, an isosceles triangle, a rhombus ..... etc.
What are the similarities between an equilateral triangle and a right triangle?
- Like all triangles, the angles must total to 180 degrees. - Both have the same formula for their areas, although the height of an equilateral triangle must be calculated from the side length. - Both have at least 2 acute angles (all three are 60 degrees in an equilateral triangle) and no obtuse angles. - Both figures have three sides. - Both figures have three angles.
How many edges are there on an equilateral triangle?
An equilateral triangle has sides and angles. There are 3 sides in any triangle. Edges are in three dimensional figures.
What is the name of a triangle which all sides have right interior angles?
Such a triangle cannot exist in 2 dimensions, the normal domain in which triangles are defined.
