Option 1: $\frac{11}{7}$

Option 2: $\frac{16}{7}$

Option 3: $\frac{25}{7}$

Option 4: $\frac{19}{7}$

Team Careers360 27th Jan, 2024

Correct Answer: $\frac{25}{7}$


Solution : We know if $\operatorname{cosec}x + \cot x = a$, then $\operatorname{cosec} x - \cot x = \frac{1}{a}$
Given, $\operatorname{cosec} A+\cot A=7$ ........(1)
⇒ $\operatorname{cosec} A-\cot A=\frac17$ .........(2)
Solving these equations to get the value of $\operatorname{cosec} A$
(1) + (2), we get,

Question : DE is tangent to the circumcircle of $\triangle$ABC at the vertex A such that $DE \parallel BC$. If AB = 17 cm, then the length of AC is equal to:

Option 1: 16 cm

Option 2: 16.8 cm

Option 3: 17.3 cm

Option 4: 17 cm

Team Careers360 27th Jan, 2024

Correct Answer: 17 cm


Solution :
Given: DE || BC and AB = 17 cm.
From the alternate segment theorem, we get $\angle$DAB = $\angle$ACB
Also, $\angle$DAB = $\angle$ABC (Alternate angle)
So, $\angle$ACB = $\angle$ABC
⇒ AB = AC = 17 cm
Hence, the correct answer is 17 cm.
