Yes
Since the sum of a triangles angles equals 180, 180-45-85=50. The angle is 50 degrees.
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
NO
Are said to be supplementary.
540 degrees. Draw line segments to connect vertices and make trianlges. You will have three triangles. Since each triangle has 180 degrees and there are three of them (180 x 3) the answer is 540 degrees. A square or rectangle has four right angles of 90 degrees each (90 x 4) and therefore it is 360 degrees. You can make two triangle when you draw a diagonal line. Each triangle is 180 degrees and equals 360 degrees.
180
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.
A triangle has three sides and three angles. Right angled triangles are triangles in which the measure of one angle equals 90 degrees
Assume each side forms the base of an isosceles triangle with its peak at the center, so the entire figure is 21 triangles with their tips all meeting. The center has 360 degrees divided by the 21 tips of the triangles, so each tip is 360/21 = 17.143 degrees. This means that the base angles of each triangle are 81.429 degrees (180 - 17.143 = base angles sum to 162.857, divide by two since they're congruent and each angle = 81.429 degrees). Since the interior angle equals the sum of the base angles of two adjacent triangles, the answer is 81.429 * 2 = 162.857 degrees.
The sum of the internal angles always equals 180o
the sum of the angle sin one triangle is 180, so the sum in three triangles would be 180x3, which is 540 degrees. Hope i helped XD
they are both 4 sided figueres...both figures angles add up to 360 degrees, they both have congruent angles (square has 4 equals,rhombus has 2 pairs)
The easiest way to find out how many degrees in any shape is 180*(n-2) where n equals the number of angles in the shape. Thus, triangles have 180 degrees.
The total angles will be 3600 degrees, because each triangle will have 180 degrees total.
Those are called 'scalene' triangles.
Let's look at an right isosceles triangle (where the base angles measure 45 degrees, and legs are congruent). So that, tan 45 degrees = leg/leg = 1
2700⁰/180⁰ = 15 (triangles)So the polygon has 17 sides.
