It is a rule that alternate angles are equal, so using this fact, we can say that: 3x + 17 = x + 53 - x 2x + 17 = 53 - 17 2x = 36 ÷ 2 x = 18 Which means that your answer would be B. x = 18 I hope this helps!
C^2=a^2+b^2 6^2=5^2+b^2 36=25+b^2 b^2=36-25 b^2=11 b= √11 b=3.3166 If you need to round it to the tenth place, b~3.3 to hundreds place, b~3.32 Good luck
