Answer:
x = 37°
x = 40°
x = 260°
Step-by-step explanation:
To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.
Question 1
[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]
Question 2
To find the bigger arc, subtract the smaller arc from 360°
⇒ 360° - 140° = 220°
[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]
Question 3
The smaller arc can also be found by subtracting the external angle from 180°
Smaller arc = 180° - 80° = 100°
[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]
[tex]160^{\circ}=x-100^{\circ}[/tex]
[tex]x=260^{\circ}[/tex]
#1
2x=128-542x=74x=37°#2
Bigger Arc=360-140=220°
2x=(220-140)2x=80x=40°#3
Smaller arc=180-80=100°
2(80)=x-100160=x-100x=260°Related Questions
What happens to a 44-degree angle if you rotate it 90 degrees counterclockwise?
Answers
Answer:
We will have a new angle \theta_{new}=143^{\circ}θ
new
=143
∘
Step-by-step explanation:
If we rotate this angle 90 degrees counterclockwise we just need to add both angles, which means:
\theta_{new}=44^{\circ} + 99^{\circ}=143^{\circ}θ
new
=44

The answer is 192.33
Step-by-step explanation:
A coaster measures 7 cm in diameter. The total area of five roller coasters must be determined.
The diameter of the coaster is d = 7 cm
The radius is:
[tex]r =[/tex] [tex]\frac{d}{2}[/tex]
[tex]=[/tex] [tex]\frac{7}{2}[/tex] [tex]cm[/tex]
[tex]= 3.5[/tex] [tex]cm[/tex]
The area of the circle is:
[tex]A =[/tex] [tex]\pi r^{2}[/tex]
= (3.14 x 3.5^2) [tex]cm^{2}[/tex]
[tex]= 38.465[/tex] [tex]cm^{2}[/tex]
We now know that the area required for five coasters is 5 x 38.465 [tex]cm^{2}[/tex]
[tex]= 192.325[/tex] [tex]cm^{2}[/tex]
Round 192.325 to the nearest hundredth and you'll get 192.33 as the correct answer.

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
Answers
Answer:
10 Classroom
Step-by-step explanation:
Since,
Custodian clean 2 classrooms in 15 minutes
Then ,
Let's see how many minutes does it takes for a custodian to clean for 1 classroom
To Find that we have to divide the given minutes by the given classroom.
15/2 = 7.5
Hence, in 7.5 minutes a custodian clean 1 classroom
Therefore:
Classroom to minutes:
1 = 7.5
2 = 15
3 = 22.5
4 = 30
5 = 37.5
6 = 45
7 = 52.5
8 = 60
9 = 67.5
10 = 75
11 = 82.5
Hence, we round to the nearest number:
which is 10 classroom in 75 minutes.
For this reason, the answer is about 10 classroom

The number of purple T shirts that the Trenton's scouting group made is 15.
What is a Pie Chart?A pie chart is a type of graph where a circle is divided into certain sectors where each sector shows a proportion of the whole.
Given is a pie chart or circle graph.
This shows the number of different colored T shirts that the Trenton's scouting group made.
Total number of T shirts = 100
Total degree of a circle = 360°
The circle is divided in to various sections with each section of different degree.
Angle measure for the purple section = 54°
Proportion of purple T shirts to the full T shirts = 54 / 360
= 0.15
Number of purple T shirts in total of 100 T shirts = 0.15 × 100
= 15
Hence the number of purple T shirts made is 15.

Help with the math question please
Answers
Answer:
a) Infinite solutions = intersect at every point (2 of the same line)
m = rise/run = 3/2
b = y-intercept = (0, -3)
y = 3/2x - 3
b) No solutions = no point of intersection (parallel lines)
m = 3/2 (same slope b/c parallel)
b = (0, 2)
y = 3/2x + 2
c) One solution = one point of intersection
Solution = (4, 3)
y - y₁ = m (x - x₁)
y - 2 = m (x - 2)
m = [tex]\frac{y2-y1}{x2-x1}=\frac{3-2}{4-2} =\frac{1}{2}[/tex]
y - 2 = 1/2 (x - 2)
y = 1/2x + 1
Check to see if (4, 3) is the solution to the system:
y = 1/2x + 1
y = 3/2x - 3
1/2x + 1 = 3/2x - 3
1 = 2/2x - 3
x = 4 ✅
y = 1/2(4) + 1 = 3 ✅

As A has angles 90,25 and 65 and B has angles 90,45 and 45, there are no two pairs of angles that are similar. Also as the angles are not equal the sides can't also be equal. So none of the above three methods are applicable here.

Find the area of the rug. DO NOT ROUND.
Answers
Answer:
28.26 ft²
Step-by-step explanation:
Formula
Area = πr²Given :
Diameter = 6 ft⇒ Radius = 3 ft [Diameter = 2 x Radius]Solving :
Area = 3.14 x 3 x 3Area = 3.14 x 9Area = 28.26 ft²Answer:
28.26 feet²
Step-by-step explanation:
Substitute the radius in the formula:
⇒ Area of circular rug = πr²
⇒ Area of circular rug = π(6/2)² [Diameter/2 = Radius]
Simplify the R.H.S:
⇒ Area of circular rug = π(3)²
⇒ Area of circular rug = π(9) [(3)² = 3 × 3 = 9]
Take π as 3.14 and simplify:
⇒ Area of circular rug = (3.14)(9)
⇒ Area of circular rug = 28.26 feet² (Using calculator)
