From the picture attached,
Statements Reasons
1). In ΔABC, DE intersects AB and AC 1). Given
2). DE║BC 2). Given
3). ∠ADE ≅ ABC 3). Corresponding angles postulate
4). ∠AED ≅ ∠ACB 4). Corresponding angles postulate
5). ΔADE ~ ΔABC 5). AA similarity postulate
6).
6). Definition of two similar triangles
Hence proved.
(x-4)^2+(y-0)^2=3^2 is the answer
The absolute value of B is 1 3/5 because although B is in the negatives, absolute value makes it positive.
