Question

please help me in 3,4,5​

Answer 1

Step-by-step explanation:

${135}^{ o} = \frac{r }{ \frac{\pi}{2} } \\ = r = { \frac{135\pi}{2} }^{c}$

${ \frac{5\pi}{9} }^{c} = { \frac{d}{90} }^{o} \\ d = { \frac{5\pi \times 90}{9} }^{o} = {50\pi}^{o}$

${50}^{g} = { \frac{2c}{\pi} }^{c} \\ c = { \frac{50\pi}{2} }^{c} = {25\pi}^{c}$
