Suppose you are given one angle A and the ratio is R so that the other two angles are B and BxR.
Then: A + B + BxR = 180.
B (1 + R) = 180 - A
so the answer is B = (180 - A) / (1 + R)
e.g. you are given A=60 and R=2
so B = (180 - 60) / (1 + 2) = 40 and the last angle is 80.
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.
Right angles aren't formed by other angles - it is already an angle itself. However, if you bisect a right angle, it becomes two acute angles.
it is impossible to do because you need at least 2 angles to tell the other one All unknown sides and angles of a triangle can be found only when one side and two angles, two sides and the included angle, two sides and an angle opposite one of them, or three sides are given. All you will know is that the sum of the other two angels is 180 - (value of known angle).
Well, first of all, the angle sum of a triangle is 180o therefore all three angles must equal that.You will most likely get given degree of two angles and will be left with an unknown one. This will be worked out by:Adding the two angles together = _______Subtract that answer by the angle sum of a triangle 180o.That's your answer...hope this helped :)
The opposite angles of a rhombus are congruent. So the angle opposite to the given angle is also 35 degrees. The consecutive angles of a rhombus are supplementary (add up to 180 degrees). So the supplement angle of the given angle is 145 degrees (180 - 35), and the angle opposite to that angle also will be 145 degrees.
180 minus two known angles = unknown angle
A right angle triangle has three sides and three interior angles one of which is 90 degrees. The names of its sides are the adjacent the opposite and the hypotenuse and using the 3 trig ratios we can find the interior angles or lengths of the sides depending on the information given.Tangent angle = opposite/adjacentSine angle = opposite/hypotenuseCosine angle = adjacent/hypotenuseIf we are given the lengths of 2 sides we can work out the angles with the above ratios.If we are given a length and an angle we can work out the lengths of the other 2 sides by rearranging the above ratios.
You use the information you're given, along with the rules, equations and formulas you know that relate the given information to the unknown angles, to find the angles.
call the small angle x, then given the ratios we have x+2x+3x=180 6x=180 so x=30 The angles are 30, 60, and 90.
Remote interior angles
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.

All the angles of a square are 90 degrees.
They can be: acute, right angle, obtuse or reflex
