The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.
83.8 degrees, approx.
Its 3rd angle is 52 degrees which is its smallest angle and opposite to its smallest side and by using the sine rule the perimeter of the triangle works out as 44.45 mm to two decimal places
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
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
So it's an equilateral triangle, what's the stumper?
If the vertex angle measures 36 degrees, then each base angle is 72 degrees, regardless of the length of the congruent sides. They may be the length of a DNA strand, a 57 Chevy, or the distance to the Andromeda Galaxy. It doesn't matter. The base angles are still 72 degrees.
A right triangle that is also isosceles cannot have an angle of 57 deg 24 sec unless it is in spherical - as opposed to plane, or flat - space.
Its 3rd angle is 52 degrees which is its smallest angle and opposite to its smallest side and by using the sine rule the perimeter of the triangle works out as 44.45 mm to two decimal places
A triangle with angles 103 degree, 20 degree, and 57 degree is called
The angles are 90 degrees, 57 degrees and the third angle is 33 degrees
It could be described as an acute triangle since each angle is less than 90 degrees. Each angle is different, and the same for length of sides, so this could also be called a scalene triangle. It's an acute scalene triangle.
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
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
Sum of all the angles in the triangle has to be 180 degrees. Let's mark the largest angle as x. Then, smallest angle will be 0.5x and the middle one x-25. x + 0.5x +x - 25 = 180, which is after simplyfying: 2.5x = 205 x = 82 degrees -> the largest angle, x-25 = 57 degrees -> middle one, 0.5x = 41 degrees -> the smallest angle.
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
It is: 180-61-62 = 57 degrees
So it's an equilateral triangle, what's the stumper?
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
