So in order to find x you need to make an equation like so.
6x + 4x + 10 = 90 (the 90 is from the right angle) You then combine like terms. 10x + 10 = 90 To isolate the variable you need to subtract 10 to both sides leaving you with... 10x = 80 Then you divide 10 from both sides and your final answer is x=8. Lets check our work shall we??? 6(8) +4(8) + 10 = 90 48 + 32 + 10 = 90 48 + 42 = 90 90 = 90 It is a solution! Yayyyyy!!!! So 8 is your answer. I hope this helps love! :)
