If triangles AMN and ABC are similar, then
AM/AB = AN/AC
or
AM/(AM + MB) = AN/(AN + NC)
Check if this is true:
AM/AB = 21/(21 + 9) = 21/30 = 7/10
AN/AC = 14/(14 + 6) = 14/20 = 7/10
The angle at vertex A is common to both of the triangles.
Then by the side-angle-side (SAS) similarity theorem, the triangles are indeed similar.
Answer:
3 1/4 inches
Step-by-step explanation:
22 3/4 ÷ 7
21÷7=3
1 3/4 = 7/4
7/4= 1/4+1/4+1/4+1/4+1/4+1/4+1/4
3 1/4 inches
Answer:
25 m = 25 × 100 = 2500 cm
5 ÷ 5 = 1
2500 ÷ 5 = 500
5:2500 ratio simplified is 1:500
Step-by-step explanation:
Answer:
252
Step-by-step explanation:
if you go around the faces, 20*5 is 100, 20*4 is 80, 20*3 is 60, 2*3 is 6 and another 2*3 is 6. add these together
