CAN SOMEONE HELP. i will give 150 points if some one can explain and solve you have to find the missing angle measures.
Tems11 [23]

Answer:

\angle ACB=40^{\circ}, \angle ABC=63^{\circ}

Step-by-step explanation:

Finding x:

We know that \angle DAB=180^{\circ}, because it's a straight line. So, \angle CAB=180^{\circ}-103^{\circ}=77^{\circ}.

We know that the sum of the angles of any triangle will be 180^{\circ}.

So, we have that (3x-14)+(3x+9)+77=180.

Combining like terms on the left gives 6x+72=180.

Subtracting 72 from both sides gives 6x=108.

Dividing both sides by 6 gives x=18.

Finding missing angle measures:

\angle ACB=3x-14=3(18)-14=54-14=40.

\angle ABC=3x+9=3(18)+9=54+9=63.

So, \angle ACB=40^{\circ} and \angle ABC=63^{\circ} and we're done!

Note: \angle ACB+\angle ABC=\angle CAD. Coincidence? If not, try and prove it!

TIMING THE CAR
kenny6666 [7]

We can define the speed as the quotient between the distance moved, and the time it takes to move that distance, so we have:

<u>speed = Distance/Time.</u>

Now we can rewrite this as:

<u>Distance = Speed*Time.</u>

We will find that the speed of the car was 21 mi/h.

Here the information given is:

Mr. Pipkins speed is: S = 3.5 mi/h

The car needed 27 "steps" to reach the corner.

Mr. Pipkins needed 27 + 135 = 162 "steps" to reach the same corner.

Because the number of steps is related to time and distance, the ratio between the number of steps should be the same as the ratio between the speeds:

162/27 = 6

(Pipkins needed 6 tomes more steps than the car, so the car moves 6 times faster than Pipkins)

This means that the speed of the car is 6 times larger than the speed of Mr. Pipkins.

Then the speed of the car is:

S' = 6*(3.5 mi/h) = 21 mi/h.

Come some one please help me ??
mariarad [96]

Answer:

B). Jarrod paid $1335 more than the Page in taxes.

Step-by-step explanation:

Given that Jarrod's filing status on last year's tax return was single, while Paige's was Head of Household. If both head taxable incomes of $80,456. Now we need to find about how did the amount's of taxes they paid compare according to the table given below.

To find that we just need to find tax value from the table and find their difference.

Tax for Jarrod = $16,306

Tax for Paige = $14,971

Difference = 16306-14971 = $1335

Hence choice B) is correct.
