Question

INNINGS 11.3
if three angles of a quadrilateral are equal and the fourth angle is a right angle, then find the three
angles of the quadrilateral
​

Answer 1

Answer:

90°

Step-by-step explanation:

3*x°+90°=360°

x is one of the three angles of quadrilateral and sum of all the angles of quadrilateral is 360° so x comes out to be 90°

Answer 2

Answer:

let the 3 equal angles be equal to x

then x+x+x+90=360. (the sum of all angles of quadrilateral is 360)

3x +90=360

3x=270

x=90
