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!
An angle that measured 145 degrees would be considered an "obtuse" angle because its measurement exceeds 90 degrees. Anything below 90 degrees would be considered an "acute" angle.
90-78= 12 degrees
An angle of 145 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees.
One fourth of 90o = 90/4 = 22.5o
An angle of 78 degrees is an acute angle because it is greater than 0 but less than 90 degrees.
It is: 47 degrees
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 4th angle is: 360-90-145-78 = 47 degrees
110 degrees.
90-78 = 12 degrees
An angle that measured 145 degrees would be considered an "obtuse" angle because its measurement exceeds 90 degrees. Anything below 90 degrees would be considered an "acute" angle.
78 is an acute angle as it is less than 90, 144 is an obtuse angles as it is between 90 and 180
An angle of 145 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees
90-78= 12 degrees
An angle of 145 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees.
A 145-degree angle is an obtuse angle, meaning it is greater than 90 degrees but less than 180 degrees. It is formed when two lines intersect and the angle between them measures 145 degrees. In geometric terms, a 145-degree angle is classified as an obtuse angle due to its measurement falling between 90 and 180 degrees.
A right angle is 90 degrees. One fourth of a right angle is, therefore, 90/4 = 22.5 degrees.
