1 answer:
Sveta_85 [38]3 years ago

Answer:

14.125

Step-by-step explanation:

You combine the two equations and get

8x - 23

and since they're in a 90 degree angle you do

8x - 23 = 90

 add 23 to both sides

8x =113

divide 113 by 8 and you get 14.125 and if you plug it in for both x's you get 24.625 + 65.375 you get an even 90
