19. ABD is a triangle right angled at Aand AC is perpendicular to BD thenshow that AC2=BC x DC |
|
Answer» Answer: (i) In ΔADB and ΔCAB, we have ∠DAB = ∠ACB (Each equals to 90°) ∠ABD = ∠CBA (Common angle) ∴ ΔADB ~ ΔCAB [AA similarity criterion] ⇒ AB/CB = BD/AB ⇒ AB2 = CB × BD In ΔCBA, ∠CBA = 180° - 90° - x ∠CBA = 90° - x Similarly, in ΔCAD ∠CAD = 90° - ∠CBA = 90° - x ∠CDA = 180° - 90° - (90° - x) ∠CDA = x In ΔCBA and ΔCAD, we have ∠CBA = ∠CAD ∠CAB = ∠CDA ∠ACB = ∠DCA (Each equals to 90°) ∴ ΔCBA ~ ΔCAD [By AAA similarity criterion] ⇒ AC/DC = BC/AC ⇒ AC2 = DC × BC (iii) In ΔDCA and ΔDAB, we have ∠DCA = ∠DAB (Each equals to 90°) ∠CDA = ∠ADB (common angle) ∴ ΔDCA ~ ΔDAB [By AA similarity criterion] ⇒ DC/DA = DA/DA ⇒ AD2 = BD × CD Step-by-step explanation: HOPE it helped you friend if it helps you mark it as brainliest |

If a=5andb=6,find the value of the following. 5a²b+7a |
Answer» Given :–
To Find :–
Solution :–Here given that,
Now put the given value in the given equation. So, our equation is, • 5a²b + 7a ⟹ 5(5)²(6) + 7(5) We know that, • 5² = 5 × 5 = 25 So, ⟹ 5(25)(6) + 7(5) Now, open the brackets. ⟹ 30(25) + 35 Again, open the bracket. ⟹ 750 + 35 Now, ADD both the numbers. We obtain ⟹ 785 Hence,Value of the given equation with the given values of a and b is 785. |
