QUESTION 1: What are the values of cos α and tan α, if α is an acute angle in a right triangle: sin α = 40/41 -------- cos α = ?
zhuklara [117]

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:

<h3 /><h3>Question 1:</h3>

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

<h3>Question 2:</h3>

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
