Os ângulos da base são congruentes... A soma dos ângulos internos do triângulo é 180º x + x + 74 = 180 2x = 180 - 74 2x = 106 x = 106/2 x = 53º (ângulos da base)
To find your answer you first have to multiply the numbers that aren’t in parentheses and you multiply 2 and 7 and you get 14 then you don’t have to worry about the x because it is a variable so now add -4 +2. but first we have to turn negative into positive so you add -4 + 8
