Question 24
ΔABC is right angled at B. If m∠A = 45°, then find the value of (cosecC + 1/√3).
Solution
Sum of angles of $$\triangle$$ ABC = $$\angle A+\angle B+\angle C=180^\circ$$
=> $$45^\circ+90^\circ+\angle C=180^\circ$$
=> $$\angle C=180^\circ-135^\circ=45^\circ$$
To find : $$(\cosec C + \frac{1}{\sqrt3})$$
= $$cosec(45^\circ)+\frac{1}{\sqrt3}$$
= $$\sqrt2+\frac{1}{\sqrt3}=\frac{(\sqrt6+1)}{\sqrt3}$$
=> Ans - (D)
