Add all angles together and minus from 360 degrees
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
The 4 interior angles of a quadrilateral add up to 360 degrees. 360-65-90-60 = 145 degrees which is the missing angle
To find the measure of the missing angle in a quadrilateral, you can use the fact that the sum of the interior angles in any quadrilateral is 360 degrees. If you know the measures of the other three angles, simply add them together and subtract that sum from 360 degrees. The result will give you the measure of the missing angle. If you provide the specific angles, I can help you calculate it directly!
Subtract 300 from 360.
The area of a quadrilateral can be calculated using various methods depending on its type. For a general quadrilateral, you can use the formula: Area = 1/2 × (d1 × d2) × sin(θ), where d1 and d2 are the lengths of the diagonals and θ is the angle between them. For specific quadrilaterals, such as rectangles or parallelograms, the area can be found using length × width or base × height, respectively. If the quadrilateral is irregular, the area can also be calculated by dividing it into triangles and summing their areas.
If you have the lengths of all three sides than ÐA = cos-1[(b2 + c2 - a2)/2bc] where a, b and c are the lengths of the sides and A is the angle opposite side a.
Sum of angles in a quadrilateral is 360° Three angles sum to 80° + 120° + 65° = 265° Therefore the missing fourth angle is 360° - 265° = 95°
360/number of sides = each exterior angle
360/number of sides = each exterior angle
a quadrilateral with no right angle is?
Doesn't work that way, sorry.
A quadrilateral is a shape with four sides... It doesn't have *one* angle. The sum of the interior angles of a quadrilateral will always be 360 degrees, however, it is impossible to know the value an individual angle of a quadrilateral with the information given.
