Two equilateral triangles differ in their side lengths by 105m The perimeter of the larger triangle is 983m Determine the side length of the smaller triangle by representing it like an equation?
Let the sides of the smaller triangle be x:- x = (983/3)-105 x = 222 and 2/3 meters or 222.666 .... recurring
What is the length of one side if the perimeter of a rhombus is 105 dm?
Each side of the rhombus will have a length of 105/4 = 26.25 dm
How do you make 105 degrees angle with compass?
105 = 90 + 15 15 = 30/2 and 30 = 60/2 you can draw 90° Draw segment AB you can draw 90° at A by drawing perpendicular bisector at A draw equilateral triangle on left side of A will give you 60° bisect 60° twice to give 15° so total angle is 90 + 15 = 105°
What is the perimeter of a standard football field?
Since the dimensions of a standard football field are 105 x 68m, and a football field is a rectangle, then 105 + 68 + 105 + 68 = 346, so the perimeter is 346m.

What is a complex shape with an area of 105 cm and a perimeter of 100 cm?
It need not be a complex shape. You can have a rectangle with these properties. Just solve the two equations: 2a + 2b = 100 (for the perimeter) ab = 105 (for the area)

The width of a rectan is 4the perimeter is 105find the length?
Let the length be known as x: 2(x+4) = 105 2x+8 = 105 2x = 105-8 2x = 97 x = 48.5 Length = 48.5 units
What is the third angle of a triangle whose first two angles are 34 and 105?
The inside angles of a triangle always add up to 180. So, if you add the two angles you do have (105 + 34 = 139), you can find out the third:180 - 139 = 41
