Answer:

Question 1:

cos a = 0.2195

tan a = 4.445

Question 2:

sin a = 0.8

tan a = 1.333

Step-by-step explanation:

Question 1:

Given that;

sin a = 40/41

a = sin ⁻¹ (40/41)

a = 77.32°

Now we have to find the value of cos a and tan a:

a = 77.32°

cos 77.32° = 0.2195

tan 77.32° = 4.445

Question 2:

Given that;

cos a = 0.6

a = cos ⁻¹ (0.6)

a = 53.13°

Now we have to find the value of cos a and tan a:

a = 53.13°

sin 53.13° = 0.8

tan 53.13° = 1.333
