Define x:
Let angle a be x.
angle a = x
angle b = 3x + 32
angle c = x + 58
Find x:
Angles in a triangle add up to 180°:
x + 3x + 32 + x + 58 = 180
Combine like terms:
5x + 90 = 180
Take away 90 from both sides:
5x = 90
Divide by 5 on both sides:
x = 18°
Find the angles:
angle a = x = 18°
angle b = 3x + 32 = 3(18) + 32 = 86°
angle c = x + 58 = 18 + 58 = 76°
Answer: The angles are 18°, 86° and 76°.
First, we need to add up all the quantities in ounces. 10 + 14 + 40 = 64. One pound = 16 ounces. 64 / 16 = 4, so the total weight in pounds is 4 lbs.
(x,y)
domain is inputs (normally x or first number)
range is outputs from the given domain (normally y or second number)
domain is just all the first numbers
range is all the second numbers
ignore repeats
domain: {0,4,5}
range: {2,3,5,7}
Answer:
a.
b.
Step-by-step explanation:
Remember that for any curve 
The tangent vector is given by
And the normal vector is given by
a.
For this case, using the chain rule
And also remember that
Therefore
Similarly, using the quotient rule and the chain rule
And also
Therefore
Notice that
1. 
2. 
b.
Simlarly
and
Therefore
Then
and also
And since
Answer:
(3,2) I think
Step-by-step explanation:
X= 3
Y=2
3 +2 =5
3-2=1
