No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
'a' and 'b' must both be acute, complementary angles.
equilateral acute
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.
right triangle and the other angle would be 70 degrees. Hope I helped :)
A triangle with no right angle and sides of different lengths is a scalene triangle.
Not always, but it is possible. An obtuse triangle has 1 angle which measures greater than 90 degrees. A scalene triangle has all different lengths in size. It is possible for a triangle to have different angles, with one above 90 degrees, and have all different side lengths.
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
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.
By using trigonometry that is applicable to a right angle triangle.
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.

Yes normally, a scalene triangle is an example.
The study is called trigonometry.
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
true
'a' and 'b' must both be acute, complementary angles.
