Acute

Angle ∠ A = α = 25.385° = 25°23'6″ = 0.443 rad

Angle ∠ B = β = 73.004° = 73°14″ = 1.274 rad

Angle ∠ C = γ = 81.611° = 81°36'41″ = 1.424 rad

Answer:

• General equation of a line:

${ \tt{y = mx + b}} \\$

${ \tt{ - 7 = ( \frac{2}{5} \times - 4) + b }} \\ \\ { \tt{ - 7 = - \frac{8}{5} + b}} \\ \\ { \tt{b = - \frac{27}{5} }}$

• Therefore, equation of line is:

${ \tt{y = \frac{2}{5}x - \frac{27}{5} }} \\$
