Ben has 5 times Cindy's money, so he has d*5=5d dollars.

Anna has $32 more than Ben, so she has 5d+32 dollars.

Hope this helps!

Hi there, hope everyone is well and staying cool :D
gogolik [260]

Answer:

A) By using the Pythagorean Theorem, we will see that 8^2 + 15^2 = 17^2. If we simplify it, we will find that the hypotenuse of ΔABC = 17

B) approximately 18.79

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is  leg^2 + leg^2 = hypotenuse^2

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, 8^2 + 17^2 = AD.  

  • 8^2 + 17^2 = 64 +289
  • 64 + 289 = 385
  • \sqrt{385} \\ ≈ 18.79

Hope you do well on the rest of your math problems :D

The sum of the angles in a hexagon is 720°.
qwelly [4]

Given:

The sum of the angles in a hexagon is 720°.

m\angle A=90^\circ,m\angle B=126.87^\circ,m\angle C=(3x)^\circ,m\angle D=90^\circ, m\angle E=143.13^\circ, m\angle F=143.13^\circ.

To find:

(a) Equation to solve the value of x.

(b) The value of x.

(c) The measure of angle C.

Solution:

(a)

We have,

m\angle A=90^\circ,m\angle B=126.87^\circ,m\angle C=(3x)^\circ,m\angle D=90^\circ, m\angle E=143.13^\circ, m\angle F=143.13^\circ.

The sum of the angles in a hexagon is 720°.

m\angle A+m\angle B+m\angle C+m\angle D+m\angle E+m\angle F =270^\circ

90^\circ+126.87^\circ+(3x)^\circ+90^\circ+143.13^\circ+143.13^\circ =270^\circ

90+126.87+(3x)+90+143.13+143.13 =720

Therefore, the required equation is 90+126.87+(3x)+90+143.13+143.13 =720.

(b)

On solving the above equation, we get

593.13+3x =720

3x =720-593.13

3x =126.87

Divide both sides by 3.

x =\dfrac{126.87}{3}

x =42.29

Therefore, the value of x is 42.29.

(c)

We need to find the measure of angle C.

m\angle C=(3x)^\circ

m\angle C=(3\times 42.29)^\circ

m\angle C=126.87^\circ

Therefore, the measure of angle C is 126.87 degrees.
