Well if its a quadrilateral it has four side. then use this. (n-2)180. Plug in your 4 sides and then its 180 times 2 . which is 360. if all of this add up to 360 then it could be porable that it will be right.
It is: 47 degrees
The 4th angle is: 360-90-145-78 = 47 degrees
The 4 interior angles of a quadrilateral add up to 360 degrees. 360-65-90-60 = 145 degrees which is the missing angle
No.
To find the measurement of the fourth angle in a quadrilateral when three angles are given, you can use the property that the sum of all angles in a quadrilateral is always 360 degrees. Given that the three angles are 90, 145, and 78 degrees, you can add these together and subtract the sum from 360 to find the measurement of the fourth angle. Therefore, the fourth angle would be 360 - (90 + 145 + 78) = 47 degrees.
The measurement for the other three angles are 107 degrees.
Well, darling, the sum of the interior angles of a quadrilateral is 360 degrees. So, if you add up 90, 145, and 78, you get 313. To find the fourth angle, you subtract 313 from 360, giving you 47 degrees. Voila!
A rhombus is a four sided quadrilateral whose total sum of interior angles amount to 360 degrees. Opposite angles are equal in a rhombus. Therefore: 35 degrees+35 degrees = 70 degrees. 360 degrees - 70 degrees = 290 degrees which then is split in two to give you the other two angles: 290/2 = 145 degrees. So the answer to your question is A 35 degrees 145 degrees 145 degrees.
180 - 35 = 145. Half of 145 is 72.5 which is the smaller angle. (The other angle is 35 + 72.5 ie 107.5)
The 2 acute angles will each measure 35 degrees
a rhombus
90 degree angle is the measure of each piece. Once the angles are formed at 145 degrees, each corner makes a 90 degree angle.
