2 right angles add up tp 180 degrees
Yes, a quadrilateral just need to have 4 sides. Quad- means 4 and -lateral means sides. To have only one tight angle, it has to be either a right angle with 2 acute angles and 1 obtuse angle OR a right angle with 2 obtuse angle s and 1 acute angle.
A triangle can have a right angle and two acute angles with all three angles adding up to 180 degrees.
What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
I'm not positive about my answer but I believe you can sort them by their angles. It can be a right angle, a triangle with angle/s exactly 90 degrees, an obtuse angle, a triangle with angle/s more than 90 degrees but less than 180 degrees. Last but certainly not the least, there is an acute angle, a triangle with angle/s less than 90 degrees. This is what I think is the answer to your question. If I didn't help you, please try to understand that: I'm not a smart person and if I was, I would've given you the right answer. I very, truly, positively am sorry if I didn't help you. And sometimes, I feel like people are taking over me so, sorry. (:
If you know the lengths of the hypotenuse (h), and one of the sides (s), then the angle next to that side (other than the right angle), is arccos(s/h). The third angle can then be calculated from the fact that all three sum to 2pi radians (180 degrees). If the lengths of the two legs of the triangle are x and y then the angle opposite the side measuring x is arctan(x/y). And again, the third angle can then be calculated from the fact that all three sum to 2pi radians. On most pocket calculators the arc functions are the same buttons as the normal trigonometric functions but you will need to press "shift" (or something) first.

If you know any two sides of a triangle (and know that one of the angles is a right angle), you can calculate the third side. Also, if you know the third side of a triangle, you can check whether the angle opposite the hypothenuse is a right angle or not.

If it is a regular nonagon, then you use the following formula: [(s-2) x 180]/s = angle of one interior angle. (s means the number of sides) Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140. Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.
Yes I had a question on my maths test asking me to draw a quadrilateral with one right angle, so yeah, a quadrilateral can have exactly one right angle lol But i havent got a clue how to draw one :S
a right angle consists of 90 degrees, so if the two acute angles in question add up to 90 degrees, than yes. For instance: two 45's a 30 and a 60 a 10 and an 80 etc
What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
Two ways to calculate the required angle. 1) Use the formula S = 2n - 4 right angles S is the sum of the interior angles of a polygon, n is the number of sides. Then, S = (2 x 15) - 4 = 26 right angles = 26 x 90 = 2340° So, each interior angle of a regular 15-sided polygon measures 2340/15 = 156° 2) Calculate the exterior angle and subtract from 180° to obtain the interior angle. Sum of exterior angles = 360° Each exterior angle measures, 360/15 = 24° Each interior angle measures, 180 - 24 = 156°
When you find the percent of something you first make it into a decimal and then you take it and move the decimal over to the right 2 time and then you add the 0's and that is your answer. ex: .3 move over to the right 2 time and then add the 0's
At first, let us define an angle in radians: Consider an arc of lenght L over an angle alfa in a circle with radius R. The angle alfa is defined as alfa=L/R [in radians]. Similarly, an stereo angle is defined in a sphere with radius R over an area S, and the stereo angle alfa is defined as: alfa=S/R^2 [in steradians]. The sphere has S=4.pi.R^2, so the corresponding angle of the sphere in steradians is alfa=S/R^2 alfa=4.pi.R^2/R^2 alfa=4.pi [steradians]
To find the time the ball was in the air, you can use the time of flight formula: T = 2 * (V * sin(angle)) / g, where V is the initial speed (31 m/s), the angle is 35 degrees, and g is the acceleration due to gravity (9.8 m/s^2). Plugging in the values, the time of flight comes out to be approximately 3.2 seconds.
