1 and 1/3 is 4/3 as a mixed number
Answer:
6=x
5.375=y
Step-by-step explanation:
You add 57° and 37° together and get 94°
You subtract the 94° from 180° (the total of the angles for all triangles) and you get 86°.
So the third angle is 86°, but it is bisected, so you divide it in half.
43=7x+1
You subtract one from both sides, giving you 42=7x
you divide 42 by 7 and get 6, so x is 6.
You divide 8 by 43 to get y.
S= -1 would make the equation true. Work is shown in the picture
