Answer:
The washer costs $626 and the dryer costs $313.
Step-by-step explanation:
Let the cost of the dryer be the base unit (1 unit).
Hence, the cost of the washer will be 2 units.
Total units = 1 + 2 = 3
3u = $939
1u = $313
The dryer costs $313.
Cost of washer = $313 × 2 = $626
The washer costs $626.

Step-by-step explanation:
Answer:
AC = 8 cm,
AD = 3 cm and ∠ACB = ∠CDA
From figure,
∠CDA = 90°
∴ ∠ACB = ∠CDA = 90°
In right angled ∆ADC,
AC2 = AD2 + CD2
⇒ (8)2 = (3)2 + (CD)2
CD2 = 64 – 9 = 55
⇒ CD = √55 cm
In ∆CDB and ADC.
∠BDC = ∠AD [each 90°]
∠DBC = ∠DCA [each equal to 90°-∠A]
∴ ∠CDB ∼ ∆ADC
Then,
