Angle a and b form a linear pair . If a-2b= 30 degree, find a and b . |
|
Answer» The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.a + b = 180a - 2b = 30By subtraction (i) and (ii)3b = 150b = 150/3 = 50a + b = 180a + 50 = 180a = 180 - 50 = 130So, a = 130 and b = 50 a=165b=15 |
