Answer:

Answer is ...Obtuse

Step-by-step explanation:

\frac{m

\frac{5x + 4}{2}  =  \frac{3}{2} x + 21

\frac{5x + 4}{2}  =  \frac{3x + 42}{2}

5x + 4 = 3x + 42

5x -  3x = 42 - 4

2x = 38

x = 19

substituting \: x = 19  \: \:in \:  \:  \:  \:  \:  \:  \: \\ m

We get,

m<ABC =

(5 \times 19) + 4 = 99

Hence <ABC is obtuse
