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

Answer:
D. 4(s + 3) & (s + 3) + (s + 3) + (s + 3) + (s + 3)
Step-by-step explanation:
We know this is a square (which is a polygon, which requires at least 3 sides), so A & B are out. C is also out because of the first expression. All 4 sides are s + 3; what the first expression on C is saying is we're adding a 5th side of 3 to 4 sides with length s. That leaves D as our answer. Bonus: Another expression that could work for this is 4s + 12 (which is both of D's expressions simplified.).
