Answer:-8/6=y
Step-by-step explanation:
You have to do KCF which means keep the number on the left or right left in this case, change the mark to a multiplication symbol, and then flip the other fraction which means 3/8 will be 8/3 and if you are looking for a mixed fraction asnwer would be -1 1/3 pls mark as brainliest if right
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,
Answer:
78cm
Step-by-step explanation:
L₁/W₁ = L₂/W₂
22/4 = L₂/6
5.5*6=L₂
L₂=33cm
Perimeter of rectangle = 2L+2W
=2(33)+2(6)
=66+12
=78cm
