a^2+b*2=c^2 

a^2+2b=c^2

  \text{Regroup terms} 

a^2=c^2-2b
  \text{Subtract 2b from both sides} 

a=\pm \sqrt{c^2-2b}  \text{Take the square root of both sides}

Use the diagram and information to answer the question.
blsea [12.9K]

Answer:There are six important properties of parallelograms to know:

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram bisect each other.

Hope this helps!! :)

Does anyone know the answer
il63 [147K]

Answer:

Both angles B and C are equal to 40°

Step-by-step explanation:

The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.

2x+10=3x-5\\10=x-5\\15=x

Now we are going to plug x back into each expression to solve for angles B and C.

Angle B

2x+10 ⇒ 2(15)+10=40

Angle C

3x-5 ⇒ 3(15)-5=40

Both angles B and C are equal to 40°

Is this enough information for Angelina to find the interest rate? Explain.
Scrat [10]
No it is not. The formula to find simple interest is Interest=Prt (p= main amount of money $300) (r= rate of interest which WOULD be a percent but is not there) (t= time aka 2 years)
