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
