7
25
find the values of coso and tano.
​

Answer 1

Answer:

Correct Question:

• If SinA = 7/25 , Find Values of CosA & TanA

Solution:

$: { \implies{ \sf{SinA = \frac{7}{25} = \frac{opp}{hyp} }}}$

• For finding CosA and TanA, We have to find Adjacent Side by using Pythagoras theorm.

$\boxed{ \sf{Pythagoras \: theorm : Hyp² = Opp² + Adj² }}$

$:{ \implies{ \sf{Hyp² = Adj² + Opp²}}} \\ \\ : { \implies{ \sf{ {25}^{2} =Adj² + {7}^{2} }}} \\ \\ : { \implies{ \sf{ {25}^{2} - {7}^{2} = Adj²}}} \\ \\ : { \implies{ \sf{Adj² = 625 - 49}}} \\ \\ : { \implies{ \sf{Adj² = 576}}} \\ \\ : { \implies{ \sf{Adjacent \: side = 24cm}}}$

• So, Adjacent Side = 24 Cm

$\to{ \sf{CosA = \frac{adjacent} {hypotenuse} = \frac{24}{25} }}$

$\to{ \sf{TanA = \frac{opposite}{adjacent} = \frac{7}{24} }}$
