Answer:

BD = 26

The measure of angle ADB = 59 degrees

The measure of angle DEC = 118 degrees

Step-by-step explanation:

BD = 2 * EC = 2 * 13 = 26

The measure of angle ADB = 90 - 31 = 59 degrees

The measure of angle DEC = 180 - 2(31) = 180-62 = 118 degrees

Help solve equations by completing the square
Allushta [10]

x^2+10x+22=13\\x^2+10x+22-13=0\\x^2+10x+9=0\\

Now completing the square.

(x^2+10x)+9=0\\(x^2+10x+25)+9-25=0\\(x+5)^2-16=0\\(x+5)^2=16

(x+5)² = 16 is the rewritten equation... For first question btw.

For the solutions to the equation -

x+5=\sqrt{16},-\sqrt{16} \\x+5=4,-4\\x=4-5,-4-5\\x=-1,-9

x = -1,-9 is the solution, for the second question.

How do I solve (fraction) 2/3d=1/6?
IgorLugansk [536]

Answer:

  d = 1/4

Step-by-step explanation:

Multiply the equation by the inverse of the coefficient of the variable.

\dfrac{2}{3}d=\dfrac{1}{6}\\\\\dfrac{3}{2}\cdot\dfrac{2}{3}d=\dfrac{3}{2}\cdot\dfrac{1}{6}\\\\d=\dfrac{3\cdot 1}{2\cdot 6}=\dfrac{3}{12}=\dfrac{3\cdot 1}{3\cdot 4}\\\\d=\dfrac{1}{4}

????????????????????????
Fed [463]
A=10*8+((8-6)(15-10))/2
A=10*8+(2*5)/2
A=10*8+10/2
A=10*8+5
A=80+5
A=85 feet 
Therefore the answer is D

Hope this helps :)
