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.
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?
A triangle with angles measuring 103°, 20°, and 57° is classified as an obtuse triangle because one of its angles (103°) is greater than 90°. The sum of the angles in any triangle is always 180°, and in this case, 103° + 20° + 57° equals 180°. Thus, the triangle is valid and has one obtuse angle along with two acute angles (20° and 57°).
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
Remember in a right angles triangle, the right angle is 90 dgrees. The sum of the three angles in a triangle is 180 degrees. Hence x + 57 + 90 = 180 x + 147 = 180 Subtract 147 from boths sides x = 33 degrees.
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
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.
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
A triangle with angles 103 degree, 20 degree, and 57 degree is called
