given two point A(-6,7) and B(1, -2) on the XOY plane, find the distance between A and B and what is the angle that the line AB makes with the X-axis?​

Respuesta :

Answer:

AB = 11.4

the angle that the line AB makes with the X-axis: 52°

Step-by-step explanation:

AB² = AC² + CB² = 81 + 49 = 130

AB = √130 = 11.4

m∠ADE = m∠ABC

tan (∠ABC) = AC/CB = 9/7

m∠ABC = 52°

m∠ADE = 52°
