Question

) If tano = 4/3, show that (sino +coso) = 7/5​

Answer 1

Step-by-step explanation:

1. We know that tan A= Perpendicular/Base
2. But, it is given that Tan A =4/3
3. so, Perpendicular= 4 And Base =3
4. Now , applying Pythagoras theoram we get Hypotenuse = 5
5. Now, Sin A = P/H=4/5
6. Similarly, Cos A = B/H=3/5
7. Putting the values is eqn. (Sino +coso)
8. 4/5+3/5=7/5
9. Hence proved

Answer 2

Answer:

1.4

Step-by-step explanation:

Tano =4/3 (1.33)

o= Tan^-1 (1.33)

o = 53°

sino+cos0= sin53 + cos 53

                = 0.7986(approx 0.8)+0.60           (Calculated using calculator)

                1.4 (7/5)
