The measure of an inscribed circle of an angle is the measure of the intercepted arc

Mathematics
1 answer:
Andre45 [30]3 years ago
4 0

Answer:

(the statement does not appear to be true)

Step-by-step explanation:

I don't think the statement is true, but you CAN compute the intercepted arc from the angle.

Note that BFDG is a convex quadrilateral, so its angles sum to 360. Since we know the inscribed circle touches the angle tangentially, angles BFD and BGD are both right angles, with a measure of 90 degrees.

Therefore, adding the angles together, we have:

alpha + 90 + 90 + <FDG = 360

Therefore, <FDG, the inscribed angle, is 180-alpha (ie, supplementary to alpha)

4. Kristina is allowed to have a friend sleep over every 3rd weekend,
PSYCHO15rus [73]

Answer:

6

Step-by-step explanation:

You must find the least common multiple of their schedules.

The numbers 3 and 2 are their own prime factors, so the least common multiple of 3 and 2 is 6.

Six weekends must pass until they can both have someone over on the same night.

The number line below shows that the first time their sleepovers coincide is Week 6.

H-1-7-g=1 and h=12 please help me I’m so confused
miskamm [114]

Answer:

g = 3

Step-by-step explanation:

12−1−7−g=1

Step 1: Simplify both sides of the equation.

12−1−7−g=1

12+−1+−7+−g=1

(−g)+(12+−1+−7)=1(Combine Like Terms)

−g+4=1

−g+4=1

Step 2: Subtract 4 from both sides.

−g+4−4=1−4

−g=−3

Step 3: Divide both sides by -1.

−g /−1 = −3 /−1

g=3

The price of a notebook was
Pie

Old price: p1 = $ 3.90;

New price: p2 = $ 3.40.


The percentual decrease is given by

d(%) = [ (p2 - p1) / p1 ] * 100 %

d(%) = [ (3.40 - 3.90) / 3.90 ] * 100 %

d(%) = [ - 0.50 / 3.90 ] * 100 %

d(%) = - 0.128 * 100 %

d(%) = - 12.8 % (approximately)


So the price fell 12.8 % approximately.


I hope this helps. =)

abruzzese [7]

The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values

a) The equation of the least-squares regression line is \underline {\hat y = 235 \cdot x + 10835}

b) The correlation coefficient for the sample is approximately 0.351

c) The slope gives the increase in the attendance per increase in wins

Reasons:

a) From the computer regression output, we have;

The y-intercept and the slope are given in the <em>Coef</em> column

The y-intercept = 10835

The slope = 235

The equation of the least-squares regression line is therefore

\underline {\hat y = 235 \cdot x + 10835}

b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229

Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351

The correlation coefficient for the sample, r ≈ <u>0.351</u>

c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins

X²-7=0 extracting square roots​
Irina-Kira [14]

Answer:

x = ± \sqrt{7}

Step-by-step explanation:

Given

x² - 7 = 0 ( add 7 to both sides )

x² = 7 ( take the square root of both sides )

x = ± \sqrt{7}
