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.
M is a letter your welcome
Answer:
slope is -2/3
Step-by-step explanation:
Absolute value= opposite. (positive turns into negative)(negative turns into positive)
A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b
