Given that \(\frac{1}{2} \log_{10} P = 1\), find the value of P.
104
103
102
101
10-1
Correct answer is C
\(\frac{1}{2} \log_{10} P = 1\)
\(\log_{10} P^{\frac{1}{2}} = 1\)
\(P^{\frac{1}{2}} = 10^{1}\)
\(\implies P = 10^{2}\)
TR is the tangent to the circle PQR with centre O. Find the size of ∠PRT
44o
46o
60o
74o
118o
Correct answer is C
Reflex < POQ = 360° - 148° = 212°
< PRO = 360° - 330° = 30°
But < ORT = 90° \(\implies\) < PRT = 90° - 30° = 60°
