How do you find the perimeter of a rectangle with a diagonal measurement and one angle?

you use SOHCAHTOA to work out whether you need to use sine or cosine (as you already have the hypotenuse) you then use the diagonal as the hypotenuse and use the equation of either:
sin(angle)=missing side/diagonal
cos(angle)=missing side/diagonal
you then take the answer and mark it on the two sides that it applies to.
you use the value you just found along with the diagonal in the Pythagoras theorem equation (in this case it will be b2 = diagonal2-other side2). you then have the value of every side so you just add them all together.

How do your find the diagonal measurement for a 10 ft square?
Two adjacent sides of a square and the diagonal joining their ends froms a right angle triangle. The legs of the triangle are 10 ft each and the diagonal is the hypotenuse. By pythagoras, diagonal = sqrt(102 + 102) = 10*sqrt(2) = 14.142 ft (to 3 dp).
What is the total angle measurement of a hexagon?
The total angle measurement is 720 degrees.
What is the measurement of a congruent angle?
A congruent angle can also mean equal angle. So there is no set measurement of a congruent angle. Just the same as the angle it is equal to.
A quadrilateral where each angle is right angle?
a square or a rectangle
Name a quadrilateral where each angle is a right angle?
A square or a rectangle
How do you find the diagonal of a rectangle if you know the length and the angle?
You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
How do you work out the diameter of a rectangle?
The diameter of a rectangle is the same as its diagonal (angle in a semicircle is a right angle). So the diagonal forms a right angled triangle with the diagonal as the hypotenuse and two sides of the rectangle (a length and a breadth) forming the legs of the triangle. If the lengths of the sides of the rectangle are known, a simple application of Pythagoras's theorem given the measure of the diagonal.
Which figure does a diagonal always form a angle bisector a rectangle a trapezoid a square or a quadrilateral?
A diagonal always forms an angle bisector in a square. In a rectangle, trapezoid, or any other quadrilateral, a diagonal does not always bisect the angles.
How do you find the area of a rectangle from diagonal and 1 angle?
The diagonal multiplied by sin(angle) gives one side of the rectangle and the diagonal times cos(theta) gives the other. So the area is (diagonal)2 x cos(theta) x sin(theta).
Is it possible to circumscribe a 90 degree angle rectangle?
Yes and the diameter of the circle will be the diagonal of the rectangle.
What is the length of a diagonal rectangle with a length of 9 inches and a width of 3 inches?
To find the diagonal length of a rectangle use Pythagoras' theorem for a right angle triangle.
What kind of triangle does a rectangle make with a diagonal?
right triangle ( triangles with a right angle)
What is the angle measurement of a regular rectangle?
All of the angles are 90o.
Do the interior angle of a pentagon have to be the same measurement of the perimeter?
The angles of a polygon are not directly related to the measurement of the perimeter. If you measure a perimeter of a pentagon in inches and then again in centimetres, the measurement number will change but the pentagon will remain the same.
How to find the area of a rectangle from diagonal?
You need to know more...either the angle or the length of one of the sides.
How do you find the width and length of a rectangle if you only know the diagnol?
If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even the area of the rectangle.
What is the cross angle measurement of a 30x50?
It seems like you're asking about the cross angle measurement of a shape or object with dimensions 30x50. However, the term "cross angle measurement" isn't clear. Could you please provide more context or clarify your question? Are you asking for the angle between the two sides of a rectangle with dimensions 30x50? If so, please specify which angles you're referring to (e.g., angles between the longer and shorter sides, or angles between diagonal lines).
