Answer: A + 17 = 35

Step-by-step explanation:

Because both sections are equal to the same amount as 35.

The rectangle for "a" plus the rectangle for 17 put together equal the same rectangle size as 35.

PLEASE HELP I AM SO STUCK. IT IS DUE ~TOMORROW.

Answer:

$A(\triangle ABC) = 7.2\: units^2$

Step-by-step explanation:

C = (0, 7)

Since, point A lies on y-axis, so it's x coordinate will be zero. Line y = 2x + 1 passes through point A.

Therefore, plug x = 0 in y = 2x +1, we find:

y = 2*0 + 1 = 0 + 1 = 1

Hence, coordinates of point A are (0, 1).

Now, by distance formula:

$AC= \sqrt{(0-0)^2 +(7-1)^2}$

$AC= \sqrt{(0)^2 +(6)^2 }$

$AC= \sqrt{0 +36 }$

$AC= \sqrt{36 }$

$AC= 6\: units$

Length of perpendicular CB dropped from point C (0, 7) to line y = 2x + 1 or 2x - y + 1 = 0 can be obtained as given below:

$CB =\frac{|2\times 0+(-1)\times 7+1|}{\sqrt {2^2 +(-1)^2} }$

$CB =\frac{|0-7+1|}{\sqrt {4 +1} }$

$CB =\frac{|-6|}{\sqrt {5} }$

$CB =\frac{6}{2.24}$

$CB =2.68\: units$

By Pythagoras Theorem:

$AB=\sqrt{AC^2 - CB^2}$

$AB=\sqrt{6^2 - (2.68)^2}$

$AB=\sqrt{36 - 7.18}$

$AB=\sqrt{28.82}$

$AB=5.36842621\: units$

$AB\approx 5.37\: units$

$A(\triangle ABC) = \frac{1}{2} \times AB\times CB$

$A(\triangle ABC) = \frac{1}{2} \times 5.37\times 2.68$

$A(\triangle ABC) = \frac{1}{2} \times 14.3916$

$A(\triangle ABC) = 7.1958$

$A(\triangle ABC) = 7.2\: units^2$
