Solve for S 2-2s=3/4s+13 S=??

see google jam board

step-by-step explanation:

because each triangles angles all equal 180* added together, you take the 112* and minus that from 180* getting 68* then divide that my two to get 34 for each corner on the outside triangle, then because the lines are parallel you can say that the corners are the same in the slightly smaller triangle, and because every line equals 180*, you can minus 34 from 180 and get 146*

i hope this !
