63
An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.
Since the formula for the area of a triangle is: A = .5 x h x b just go 63 = .5 x b x 18 then 63 = 9b 7 = b
Anglw C is 63 degrees because the 3 interior angles of a triangle add up to 180 degrees
162+632=652 It is, in fact, a right triangle. I see no other question that you could be posing.
63 degrees because 180 -39 -78 = 63

An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.
The total internal angles of a triangle always equal 180 degrees. Therefore, the third angle of this triangle must be 180 - 54 - 63 = 63. Since this value is the same as one of the stated sides, the triangle is indeed isosceles.
The sides of a triangle always equal to 180 so 63+54 = 117 and 180 - 117 = 63. The answer is 63. Or, an isosceles triangle has 2 sides of the same length, so you know it would either be 54 or 63I hope you find this helpful :D
Since the formula for the area of a triangle is: A = .5 x h x b just go 63 = .5 x b x 18 then 63 = 9b 7 = b
It is: 90 -27 = 63 degrees
The question is missing something? 63 kg is a weight. 63 kg is 138.891225 pounds.
the total sum of the angles of a triangle should total 180 degrees so 35+28= 63 180 - 63= 117 X= 117 degrees
The third angle must be 63 degrees because all angles in any triangle add up to 180 degrees
