The figure the Floor Plan of a balcony ,it consists of △ABC and semi-circle ,

ivanzaharov [21]

Step-by-step explanation:

(a) In right triangle ABC,

$AC^2 =AB^2 +BC^2 \\ = {12}^{2} + {5}^{2} \\ = 144 + 25 \\ = 169 \\ AC = \sqrt{169} \\ \therefore \: AC = 13\: m \\ \\ AC \: is \: the \: diameter \: of \: semicircle \\ \therefore \: r = \frac{1}{2} \times AC = \frac{1}{2} \times 13 = 6.5 \: m \\ Circumference \:of \:semi-circle \\ C = \pi \: r = 3.14 \times 6.5 = 20.41 \:m\:$

Perimeter of Balcony = 12 + 5 + 20.41 = 37.41 m

(b) Area of balcony

$=\frac{1}{2}\times 12\times 5+\frac{1}{2} \pi r^2 \\\\=\times 6\times 5+\frac{1}{2} \times 3.14\times (6.5)^2 \\\\=30+\frac{1}{2} \times 3.14\times42.25\\\\= 30+\frac{1}{2} \times 132.665\\\\= 30 + 66.3325\\\\= 96.3325 \:m^2 \\\\\approx 96. 33\:m^2$

Ay/b-by/a=a^2-b^2. find value of y

klemol [59]

We can actually undsitribute the y

$y( \frac{a}{b}- \frac{b}{a})=a^2-b^2$
divide both sides by $( \frac{a}{b}- \frac{b}{a})$
$y= \frac{a^2-b^2}{ \frac{a}{b}- \frac{b}{a} }$
times the right side by (ab/ab)
$y= \frac{ab(a^2-b^2)}{ a^2- b^2 }$
y=ab

Which relationships describe the angle pair x° and 50º?

MariettaO [177]

Your answer is A and D. adjacent angles and vertical angles.

<u>Adjacent angles and vertical angles.</u>

From the given figure, it can be seen that ∠x and 50° form adjacent angle pair. using the straight line property, we have

∠x+50°+90°=180°

∠x+140°=180°
∠x=40°

Now, if we put x=40° and add with angle having measure 50°, it forms complementary angles.

Thus, <u>option a and d </u> are the correct answers.
