QRST is a square. PQ = 2√ RU = 4<br> What is the length of SU? Round to the nearest tenth.

777dan777 [17]

Answer:

$SU=3.5\ units$

Step-by-step explanation:

step 1

In the isosceles right triangle PQT

PQ=PT ----> because is an isosceles triangle

Applying the Pythagoras Theorem

we have

$PQ=PT =\sqrt{2}\ units$

$QT^{2}=PQ^{2} +PT^{2}$

substitute the values

$QT^{2}=\sqrt{2}^{2} +\sqrt{2}^{2}$

$QT^{2}=4$

$QT=2\ units$

step 2

In the square QRST

$RS=QT=2\ units$

step 3

In the right triangle RSU

Applying the Pythagoras Theorem

$RU^{2}=RS^{2} +SU^{2}$

we have

$RU=4\ units$

$RS=2\ units$

substitute the values and solve for SU

$4^{2}=2^{2} +SU^{2}$

$SU^{2}=4^{2}-2^{2}$

$SU^{2}=12$

$SU=2\sqrt{3}\ units$

$SU=3.5\ units$

Find the perimeter of the polygon. Round your answer to the nearest tenth.

lakkis [162]

Answer:

Option B.

Step-by-step explanation:

From the given figure it clear that the the vertices of the polynomial are Q(2,0), R(4,5), S(8,7), T(6,4) and U(10,3).

Distance formula:

$d=\sqrt{(x-2-x_1)^2+(y_2-y_1)^2}$

Using distance formula, we get

$QR=\sqrt{\left(4-2\right)^2+\left(5-0\right)^2}=\sqrt{29}$

$RS=\sqrt{\left(8-4\right)^2+\left(7-5\right)^2}=2\sqrt{5}$

$ST=\sqrt{\left(6-8\right)^2+\left(4-7\right)^2}=\sqrt{13}$

$TU=\sqrt{\left(10-6\right)^2+\left(3-4\right)^2}=\sqrt{17}$

$QU=\sqrt{\left(10-2\right)^2+\left(3-0\right)^2}=\sqrt{73}$

Now, the perimeter of the polynomial is

$Perimeter=QR+RS+ST+TU+QU$

$Perimeter=\sqrt{29}+2\sqrt{5}+\sqrt{13}+\sqrt{17}+\sqrt{73}$

$Perimeter=26.12996$

$Perimeter\approx 26.1$ units.

Therefore, the correct option is B.
