Question 1 Report
The interior angles of a quadrilateral are (x + 15)o, (2x - 45)o and (x + 10)o. Find the value of the least interior angle.
Answer Details
(x + 15)o + (2x - 45)o + (x + 10)o = (2n - 4)90o when n = 4 x + 15o + 2x - 45o + x - 30o + x + 10o = (2 x 4 - 4) 90o 5x - 50o = (8 - 4)90o 5x - 50o = 4 x 90o = 360o 5x = 360o + 50o 5x = 410o x = 410o5 410 o 5 = 82o Hence, the value of the least interior angle is (x - 30o) = (82 - 30)o = 52o
