The angle x is half the sum of the intercepted arcs, PQ and NO.
... (1/2)(65° + 45°) = 55° = x° = m∠PMQ

Now multiple the coefficients and add the exponents with common bases

Now write your final expression

Hope I helped!
1/9=0.11111.....
so the correct option is (a).
I need help with MY MATH jejehee
<span>It mainly means 'simplifying an expression down to a single numerical value', I believe.</span>
