If m2 3 = 9n and m24 = 24n+15, then what is the value of n?

Nataly_w [17]

Answer:

n = 5

Step-by-step explanation:

$\because m \angle \: 3 + m \angle \: 4 = 180 \degree..(supplementary \: \angle s) \\ \therefore \: 9n + 24n + 15 = 180 \\ \therefore \: 33n = 180 - 15 \\ \therefore \: 33n = 165 \\ n = \frac{165}{33} \\ \huge \red{ \boxed{\therefore \: n = 5}}$
