The 3rd angle must be 52 degrees and so by using the sine rule in trigonometry its other sides are 16.35cm and 13.62cm both rounded to two decimal places.
Therefore the perimeter of the triangle is: 14.5+16.35+13.62 = 44.47cm

What is the perimeter of a triangle when side 14.5cm is opposite angle 57 degrees and has another angle of 71 degrees?
Using the trigonometry sine rule the other sides of the triangle are 16.35cm and 13.62cm so it follows that its perimeter is 14.5+16.35+13.62 = 44.47cm
What is the perimeter of a triangle when an angle of 57 degrees is opposite a side of14.5cm and another angle is 71 degrees?
Using the sine rule in trigonometry its other sides are 13.62cm and 16.35cm both rounded to two decimal places therefore it follows that the perimeter of the triangle is 14.5cm+13.62xm+16.35cm = 44.47cm
What is the area and perimeter of a scalene triangle when angle 75 degrees is opposite to side 25cm with another angle of 42 degrees?
Using the sine rule in trigonometry its area is 192.885 square cm and its perimeter is 65.379 cm both rounded to three decimal places.
How do you find the perimeter of a scalene triangle?
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
How do you find Ares and perimeter on a tringle?
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
Non adjacent side of a triangle?
The side that is not adjacent to another side of a triangle is called the opposite side.
How do you calculate the perimeter of a triangle?
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.
How do you find the length of third side of a triangle given two sides and permeter of the triangle?
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
The Isosceles Triangle Theorem states that if two sides of a triangle are congruent then the angles opposite those sides are?
congruent to one another.
How do you figure out the perimeter of an triangle when you only have a measurement for the hypotenuse?
It is impossible. You need another measurement, such as angle, side length or area etc.
How do you calculate perimeter of a triangle?
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle. ----------------------------------- The perimeter is the sum of all three sides. Sometimes it is unnecessary to compute each side length; all we care about is the sum.
If one angle of a triangle is larger than another angle then the side opposite the larger angle is?
the smaller side
