Answer» ONG>Step-by-step EXPLANATION:

\huge{\underline{\boxed{\sf{\red{answer}}}}}

GIVEN that

\cos0 = \frac{7}{25} \: = \frac{b}{h} \\ {h}^{2} = {b}^{2} + {p}^{2} \\ here \: h = 25 \: and \: b = 7 \\ {25}^{2} = {7}^{2} + {p}^{2} \\ 625 = {p}^{2} + 49 \\ 625 - 49 = {p}^{2} \\ 576 = {p}^{2} \\ p = \sqrt{576} \\ p = 24

so we GOT that

h= 25

b=7

p= 24

therefore,

\cos + \sin \\ \frac{b}{h} + \frac{p}{h} \\ \\ \frac{7}{25} + \frac{24}{25} \\ \\ \frac{31}{25} \\ \\ \frac{31}{25} is \: the \: correct \: answer \\ hope \: it \: helps
