Answer:
A. Adding the values of the intercepted arcs and that is equal to twice the angle measure
Step-by-step explanation:
The intersecting chords theorem states that when four line segments are formed by two chords intersecting in a circle, the product of the two line segments on one chord is equal to the product of the two line segments on the other chord
The angles of intersecting chords theorem states that the angles formed by the intersecting chords one half the sum of the arcs intercepted by the chords
In the diagram attached, we have;
∠x = ∠y + ∠z
m[tex]\widehat{DHE}[/tex] = 2·∠z, m[tex]\widehat{CIF}[/tex] = 2·∠y
∴ ∠x = (1/2) × m[tex]\widehat{DHE}[/tex] + m[tex]\widehat{CIF}[/tex]
m[tex]\widehat{DHE}[/tex] + m[tex]\widehat{CIF}[/tex] = 2 × ∠x
The correct option is therefore adding the values of the intercepted arcs and that is equal to twice the angle measure.

Answer: 35 degrees
Step-by-step explanation: 180-145=35
Answer:
Hello! answer: 35 degrees
Step-by-step explanation:
That is forming a supplementary angle meaning it will add up to 180 degrees 180 - 145 = 35 therefore x = 35 HOPE THAT HELPS!

Please help how to find the value of x and find the length of segment AD, the value is 5 I just need to show my work.
Answer:
9. x = 5
10. AD = 7
Step-by-step explanation:
As shown in the diagram, BD is a perpendicular bisector. And D is a point on the perpendicular bisector, meaning it is equidistant from the endpoints on the segment(points A and C). Because of this, we can say AD = CD.
We can substitute to get:
2x - 3 = x + 2
And simplify and solve:
x - 3 = 2
x = 5
AD is just 2x - 3, so we can substitute in x to find AD:
AD = 2(5) -3
AD = 10 - 3
AD = 7

justin wants to measure the thickness of a paper towel roll but his ruler is not the proper measuring device.using a full roll he takes the measurements
Answer:
Vernier caliper
Step-by-step explanation:
The paper towel is circular in shape, should he use the ruler he may come up with a value but the value may not be accurate.
Hence the measuring instrument Justin should use is a vernier caliper, which is a measuring device that can be used to measure the external diameter of the roll of paper

There are 130 people in a sport centre.
65 people use the gym.
51 people use the swimming pool.
44 people use the track.
15 people use the gym and the pool.
14 people use the pool and the track.
10 people use the gym and the track.
1 person uses all three facilities.
A person is selected at random.
What is the probability that the person uses exactly one of the facilities?
Answer:
The probability that the person uses exactly one of the facilities is 69.23%.
Step-by-step explanation:
Since there are 130 people in a sport center, of which 65 people use the gym, 51 people use the swimming pool, 44 people use the track, 15 people use the gym and the pool, 14 people use the pool and the track. , 10 people use the gym and the track and 1 person uses all three facilities, to determine, if a person is selected at random, what is the probability that the person uses exactly one of the facilities, the following calculation must be performed:
130 = 100
130 - 1 - 15 - 14 - 10 = X
130 = 100
90 = X
90 x 100/130 = X
9,000 / 130 = X
69.23 = X
Therefore, if a person is selected at random, the probability that the person uses exactly one of the facilities is 69.23%.

Marty cuts 2.05 ounces of cheese from a 4.6 ounce block of cheddar cheese. How many ounces of cheddar cheese are left in the block
Answer:Amount of cheese left=2.55ounce
Step-by-step explanation:
Total amount of cheddar cheese =4.6ounce
Amount of cheese cut out =2.05 ounces
Amount left =Total amount of cheddar cheese-Amount of cheese cut out
=4.6ounce-2.05 ounces=2.55ounce
Andrew thought he could score 25 points on an arcade game, but he only scored 17. What was Andrew's percent error? Prediction - Actual Hint: Percent error- * 100 Actual Round to the nearest percent. [?]%
Answer:
47%
Step-by-step explanation:
% error = ( (theoretical(correct) – experimental(prediction)) / theoretical(correct) ) × 100%.
% error = |17 – 25| / 17 × 100% =
% error = (8 / 17 × 100)%
% error = (800 / 17)%
% error = (47.0588235294..)%
% error ≈ 47%

find the value of x. round to the nearest tenth
Answer:
using Pythagoras theorem x=32.7
Answer:
21.7
Step-by-step explanation:
In order to solve this problem, we can use trig functions. We are given the side adjacent to the 37° given and we are looking for the hypotenuse. This means that cosine function is the most suitable. Cosine is written as:
cos(θ°) = adjacent / hypotenuse
We can substitute the values we have:
cos(37°) = 17.3 / x
And rewrite the expression:
x = 17.3 / cos(37°)
Then, use a calculator to evaluate:
x = 21.66194689
This can be rounded to 21.7
Point S is located at (-9. 8). Point G is located at (-3. 3). Determine the
slope-intercept equation of line SG.
Please help :)
Answer:
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = S (- 9, 8) and (x₂, y₂ ) = G (- 3, 3)
m = [tex]\frac{3-8}{-3+9}[/tex] = - [tex]\frac{5}{6}[/tex] , then
y = - [tex]\frac{5}{6}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = [tex]\frac{5}{2}[/tex] + c ⇒ c = 3 - [tex]\frac{5}{2}[/tex] = [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex] ← equation of line
find the direction angle of -12i - 35j
Answer:
[tex]\theta=71.07^{\circ}[/tex]
Step-by-step explanation:
The given vector is :
v = -12i - 35j
We need to find the angle direction of v.
The general vector is given by :
v = xi+yj
The direction angle is :
[tex]\theta=\tan^{-1}(\dfrac{y}{x})[/tex]
We have, x = -12 and y = -35
So,
[tex]\theta=\tan^{-1}(\dfrac{-35}{-12})\\\\\theta=71.07^{\circ}[/tex]
So, the required direction angle is [tex]71.07^{\circ}[/tex].
hi can you guys please answer each of these questions accurately I'm kind of in a rush, so pls help as soon as you can I'm also giving out brainliest:)
Answer:
Step-by-step explanation:
(1) 6 yd 1 ft plus 9 yd 1 ft works out to 15 yd 2 ft, or 15 2/3 yd.
(2) 8' 3" less 5' 5" requires "borrowing." Since 1 ft = 12 in, your 8' 3" becomes 7' 12".
Subtracting 5' 5" from 7' 12" yields 2' 7"
(3) 25 lb 8 oz less 15 lb 10 oz also requires borrowing.
1 lb = 16 oz, so:
25 lb 8 oz = 24 lb 24 oz. Then we subtract 15 lb 10 oz from 24 lb 24 oz:
9 lb 14 oz
