This polygon has 4 sides 180(4-2) = 180(2) = 360 degree 80+90+2x + 3x = 360 170+5x = 360 5x = 190 x= 38 measure of angle t is 2(38)= 76 the answer is c. trust me hope this !
Elizabeth claims that the fourth root of 2 can be expressed as 2^m since (2^m)^n = 2. find the values of m and n for the case where elizabeth's claim is true.
