11. Determine the measure of the angles below.
12. Two lines intersect to form the four angles shown in the figure. Which term does not accurately describe the pair of angles 1 and 4?
Answers
Answer:
11 - 125 and 55
12 - supplementary
Step-by-step explanation:
5x+20+3x-8=180
step 1 combine like terms
8x+12=180
step 2 subtract 12 from each side
8x=168
step 3 divide each side by 8
x=21
then you just plug in 21 to each equation to find that angle 1 = 125 and angle 2=55
Problem 11
Answers:
5x+20 = 1253x-8 = 55--------------------
Explanation:
The two angles shown here form a linear pair. They supplementary so they add to 180.
(5x+20)+(3x-8) = 180
(5x+3x) + (20-8) = 180
8x+12 = 180
8x = 180-12
8x = 168
x = 168/8
x = 21
We then find the angles to be
5x+20 = 5*21+20 = 125
3x-8 = 3*21-8 = 55
Note how 125+55 = 180 to help confirm the answers
===================================================
Problem 12
Answer: B) Vertical angles
--------------------
Explanation:
Vertical angles are angles that form after intersecting two lines, and the angles are opposite one another. So one example of a vertical angle pairing would be angles 1 and 3. The other vertical angle pair of this diagram are angles 2 and 4. Vertical angles are always congruent to one another.
In this diagram, angles 1 and 4 are adjacent since they are next to each other. In other words, they share a common line (think of apartment neighbors sharing a common wall). Since they are adjacent angles, there is no way they are vertical angles.
Angles 1 and 4 are also supplementary since they form a straight line. They are a linear pair for very similar reasons. This allows us to rule out choices A, C and D.
Side note: the term "linear pair" means that the angles are adjacent and supplementary.

A spherical balloon is inflating with helium at a rate of 64π ft/min. How fast is the balloon's radius increasing at the instant the radius is 2 ft? How fast is the surface area increasing?
The balloon's radius is increasing at a rate of...
Answers
Answer:
let r ,v be the radius and volume of sphere.
dv/dt=64πft³/min
r=2ft
Dr/dt=?
Step-by-step explanation:
we have
volume of sphere=4/3πr²
v=4/3πr²
differentiating both side with respect to t we get
dv/dt=4πdr²/dr×dr/dt=4π×2r×dr/dt=8/3×πr×dr/dt
substituting the given value we get
dv/dt=8/3×πr×dr/DT
64π×3/(8π×2)=dr/dt
Dr/dt=12ft/min
The balloon's radius is increasing at a rate of12 ft/min
The balloon's radius increasing at the instant the radius is 2 ft will be 10106.47 ft³ per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
A spherical balloon is inflating with helium at a rate of 64π ft/min.
dr/dt = 64π ft/min
Then the balloon's radius increasing at the instant the radius is 2 ft will be
V = (4/3)πr³
Differentiate with respect to time. Then we have
[tex]\rm V' = \dfrac{dV}{dt} \\\\ V' = \dfrac{4}{3}\cdot \pi 3r^2 \cdot \dfrac{dr}{dt}[/tex]
Simplify the equation, then we have
V' = 4πr² × 64π
V' = 4π × (2)² × 64π
V' = 10106.47 ft³ per minute
The balloon's radius increasing at the instant the radius is 2 ft will be 10106.47 ft³ per minute.

A tree measured 12 1/2
feet tall. Over the next 5 1/2
years it grew to be 51 feet tall.
During the 5 1/2
years, what was the average yearly growth rate of the tree?
Answers
Answer:4.08 ft a year or 1 and 5/8 feet a year (approx)
Step-by-step explanation:
It's 12.5 feet the first year
51 feet 5 years later
If you do the math and divide 51 by 12.5, you get 4.08 which is around 1 and 5/8 ft
12.5x4.08 is 51 feet.
So the tree grows approximately 1 and 5/8 feet a year

The width of a rectangle is 2 inches smaller than its length. The perimeter is 24 inches. Find the length and width of the rectangle.
Answers
Answer:
7 inches and 5 inches
Step-by-step explanation:
The length the length and width of the rectangle be l and b.
Accodrding to question,
Width, b = l-2
Perimeter, P = 24 inches
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
24 = 2(l+l-2)
12 = 2l-2
14=2l
l = 7 inches
Width, b = 7-2 = 5 inches
Hence, the length and width of the rectangle are 7 inches and 5 inches respectively.

what is the value of y?
Answers
130 / 2 = 65
Y = 65
For the given triangle the measure of the angle y is 65°.
Hence the correct option is C.
The angles that are created outside of a triangle are its external angles.
In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's exterior angle.
And the exterior angle of a triangle is the sum of the interior angles of opposite sides.
The given angles are:
Exterior angle = 130°
Interior angles are y° and y°
Therefore,
Exterior angle = y° + y°
130° = y° + y°
2y° = 130
Dividing both sides by 2 we get,
y° = 65°
Hence,
The measure of the angle y is 65°.

12x +12y = 7
Step-by-step explanation:
The 2-point form of the equation for a line is useful.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1/3 -1/4)/(1/4 -1/3)(x -1/3) +1/4
y = (1/12)/(-1/12)(x -1/3) +1/4)
y = -x +1/3 +1/4
Add x and multiply by 12.
x +y = 1/3 +1/4
12x +12y = 4 +3
12x +12y = 7
