Mnenie [13.5K]

Answer:

30

Step-by-step explanation:

triangle ABC is proportional to triangle BCD so

hypothenuse of ABC/ ajdacent of ABC = hypotrnus BCD/ ajdacent of BCD

in short

AC/BC = BC/DC

10/x = x/3

10 . 3 = x²

x² = 30

x = √30

so the question mark is 30

4. Rhombus QRST has diagonals intersecting at W. Point U is located on side QR and point V on diagonal RT
ad-work [718]

Answer:

Given:

In Rhombus QRST, diagonals QS and RT intersect at W and U∈QR and point V∈RT  such that UV⊥QR. (shown in below diagram)

To prove: QW•UR =WT•UV

Proof:

In a rhombus diagonals bisect perpendicularly,

Thus, in QRST

QW≅WS, WR ≅ WT and m∠QWR=m∠QWT=m∠RWS=m∠TWS=90°.

In triangles QWR and UVR,

m\angle QWR=m\angle VUR              (Right angles)

m\angle WRQ=m\angle VRU              (Common angles)

By AA similarity postulate,

\triangle QWR\sim \triangle VUR

The corresponding sides in similar triangles are in same proportion,

\implies \frac{QW}{VU}=\frac{WR}{UR}

QW\times UR=WR\times VU

QW\times UR=WT\times UV                 (∵ WR ≅ WT )

Hence, proved.
