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:
14x + 6
step by step explanation:
Answer:
For number 1, it's 3(x^2+1)
Step-by-step explanation:
Step 1: Identify the GCF of the polynomial.
Step 2: Divide the GCF out of every term of the polynomial.
Step-by-step explanation:
Note the system of equation, PEMDAS. First, you solve parenthesis, then multiplication, then subtraction.
In this case, solve each of the expression given to us. Remember that parenthesis is first:
(12 - 23) * 2 = (-11) * 2 = - 22
12 - (3 * 2) = 12 - (6) = 6
- 22 ≠ 6

2.49 divied by 48 1/8
make 2.49 into an mixed number first
2 49/100.
make 2 49/100 into an improper fraction
Mutiply the whole number with the denominator
2*100= 200
Add 200 with the numerator. 200+49= 249
2 49/100= 249/100
48 1/8-make it into a improper fraction
48 1/8=385/8
249/100* 8/385
Answer: 0.05
