Step-by-step explanation:

Secant AD and AE intersect in the exterior of a circle. ∠ BAC measures 27.42° and the measure of DE is 73.18°. Determine the measure of BC .

Answers

Answer:

BC = 18.34°

Step-by-step explanation:

The secant- secant angle BAC is half the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] ( DE - BC) = 27.42

[tex]\frac{1}{2}[/tex] ( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )

73.18 - BC = 54.84 ( subtract 73.18 from both sides )

- BC = - 18.34° ( multiply both sides by - 1 )

BC = 18.34°

R
Towns P, Q and Rare connected by roads PQ, PR and QR.
PR is 15 km longer than PQ.
QR is three times as long as PR.
The total length of the three roads is 245 km
Work out the length of PQ.
Use x as the unknown in any working.
Your final line must say, PQ = ...
Pa​

Answers

Answer: 37 km

Step-by-step explanation:

Given

The total length of the three roads is 245 km

Suppose the length of PQ is  [tex]x\ km[/tex]

According to question

The Length of PR is  [tex]x+15[/tex]

The length of QR is  [tex]3(x+15)[/tex]

The Sum of PQ, PR, and QR is

[tex]\Rightarrow x+x+15+3(x+15)=245\\\Rightarrow 5x+60=245\\\Rightarrow 5x=185\\\Rightarrow x=37 km[/tex]

length of PQ=37 km

i need to know as soon as possible!! thanks

Answers

Answer:

m = 24

Step-by-step explanation:

m + 7° + 2m + 11° = 90°

3m + 18° = 90°

3m = 90°- 18°

3m = 72

(divide both sides by 3)

therefore : m = 24

90-11=79
79=2m+m+7
79=3m+7
79-7=3m
72=3m
72/3=3m/3

24=m

K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.

X   Y  

2   4

1    1

0   0

-1    1

-2   4

If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.

Three friends were playing a game of marbles. At the end of the game, Marcy had 25% of the marbles, Roger had21of the marbles, and Ann had the rest of the marbles. If there were 100marbles altogether, how many marbles did Ann have at the end of the game​

Answers

Answer:

54

Step-by-step explanation:

total no. of marbles=100

no. of marbles Marcy had

=25% of 100

=25/100×100

=25

no. of marbles Roger had=21

Let the no. of marbles Ann had=x.

So, 25+21+x=100

46+x=100

x=100-46=54

Therefore, Ann had 54 marbles at the end of the game.

The answer is y=2x+2

Answer:

y = 2x + 2

Step-by-step explanation:

First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.

(0, 2) & (6, 14)

Plug in these values:

(14 - 2) / (6 - 0)

Simplify the parentheses.

= (12) / (6)

Simplify the fraction.

12/6

= 2

This is your slope.

Now plug this into the standard slope-intercept equation: y = mx + b

y = 2x + b

b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.

Therefore, our b-value is 2.

Plug this into our equation.

y = 2x + 2

bottles. Work out an estimate for the total number of bottles that
Margaret will be able to fill with the milk.​

Answers

Answer:

Answers

Answer: the statement “measure of <4 is 105 degrees” is incorrect.

Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.
