angle a= 87.3819 DEG. (approx.)
angle b= 62.6181 DEG. (approx.)
angle c= 30 deg.
side opposite angle a= 9 cm (given)
side opposite angle b= 8 cm (given)
side opposite angle c= 4.5047 cm
this triangle is almost a 30, 60, 90 better known as a special right triangle where the side opposite the right angle is twice the size of the side opposite the 30 deg. angle so the side opposite angle b would be: 9/2 times the square root of 3.
to solve this problem (since this triangle is not really a right triangle) you must use the law of cosines coupled with the law of sines in order to solve this problem.

The legs of a triangle are 5 and 12 What is the perimeter?
With sides of 5 and 12, you can make a triangle with any perimeter you want between 24 and 34. If you call them "legs" because they are the sides of a right triangle, then the hypotenuse is 13, and the perimeter is 30.
What is perimeter of a circle called?
The length of the perimeter is the circumference. The perimeter itself is the boundary between the interior and exterior of the circle. The perimeter of a circle is called the circumference
What is an acute-angled triangle?
An acute-angled triangle is a triangle in which all the interior angles are between 1 and 89 degrees.
What is the relationship between the measure of the angles in a triangle?
The sum of the interior angles of a triangle is equal to 180 degrees.
What is the difference between length and perimeter?
Length is the distance between two different points. But perimeter is the distance between the same point. Really interesting. Isn't it? Perimeter of sqaure is 4 x side Perimeter of rectangle is 2 (length + breadth) Perimeter of triangle is a + b + c Perimeter of a circle is specially named as circumference.

What is the difference between an acute triangle and an obtuse triangle?
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles

What is the relationship between interior and exterior angles in triangles?
An interior angle of a triangle is the angle between two edges, measured inside the triangle. An exterior angle is formed by extending one of the edges outside the triangle, and measuring between that extension and the adjacent original side of the triangle. The sum of the interior angle and exterior angle at any given corner is always 1800 (which is Pi radians).

Length is the distance between two different points. But perimeter is the distance between the same point. Really interesting. Isn't it?

What is the relation between perimeter and triangle area?
If you double (2 times) the perimeter the area will will be 4 times larger. Therefore the area is proportional to the square of the perimeter or the perimeter is proportional to the square root of area. The relationship as shown above applies only to triangles with similar proportions, that is when you scale up or down any triangle of fixed proportions. Other than that requirement, there is no relationship between perimeter and area of any shape of triangle except that it can be stated that the area will be maximum when the sides are of equal length (sides = 1/3 of perimeter).
How do you find the perimeter of a triangle if 10m and 25m are the given sides?
The lengths of two sides are not enough to determine the perimeter of a triangle: Either the third side or else the angle between the two given sides is also needed. If two of the sides are 10m and 25m, then the third side can be anything between 15m and 35m, and the perimeter can be anything between 45m and 70m.
What are the realtionships between the interior and exterior angles of a triangle?
Their measure sum is 180 degrees.
What is the scale factor of two figures with a perimeter of 50 Cm and 75 Cm?
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
What is the perimeter of a square with diagonal 12 centimeters?
The perimeter of a square with a diagonal of 12 centimeters is: 33.9 centimeters.In future, to find out the perimeter of a square when you only know it's diagonal, use Pythagoras or times the diagonal by 2.828427125.This number is irrational, and is like a pi for the diagonals of squares.I call it Tau.It is the relationship between the diagonal of all squares and there perimeter.
