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
No, you do not need to know all the side lengths and angle measures to solve a triangle. You can solve a triangle using various methods, such as the Law of Sines or the Law of Cosines, if you have sufficient information, like two angles and one side (AAS or ASA), or two sides and the included angle (SAS). Additionally, having all three side lengths (SSS) is also enough to determine the triangle's angles.
