recall from the previous posting, the sum of all interior angles in a triangle is 180°.
so the third one will be 180° - 118.6° - 42.3°.
Answer:
42
Step-by-step explanation:
3.5 kilometers
35000/100 = 3500
3500/1000=3.5
I think E.
Width=4, and Length=17
first you will make a variable for the width which i will say is x
now make it an equation (3x+5) (x) = 68
then solve 3x^2+5x=68
then 3x^2+5x-68=0
then x=4
then you have to substitute so 3(4)+5= 17 and 4
0,0
