The interior triangles are similar, so the following ratio should hold true:
9 x
--- = ------ then x^2=144 and x=12 (answer)
x 16
Answer:
8/15
Step-by-step explanation:
Add: 1/5
+ 1/3
= 1 · 3/
5 · 3
+ 1 · 5/
3 · 5
= 3/15
+ 5/15
= 3 + 5/15
= 8/15
8 is approximately the greatest i think
1 = 60
2 = 120
3 = 25
triangles have total angles of 180 40+80=120
180-120=60
straight lines have total angles of 180
180-60=120
triangles have total angles of 180
120+35=155
180-155=25
