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
Well 3 x 7 + 9= 30
so 30<span> divided by 36 = 1.2
answer: 1.2</span>
Answer: 5.1 mi.
Explanation: Just multiply both of the numbers to find your answer.
1.5*3.4=5.1
Answer:
(-1, 5)
Step-by-step explanation:
Rearrange the the first equation to have y on one side and all other values on the other side
y = 1 - 4x
since both of the equations are equal to y, set them equal to each other an solve for x.
1 - 4 x = x + 6
-5 = 5 x
x = -1
plug this back into the second equation to get y = 5
