दो पूरक कोणों के माप का अंतर 12° है। यदि छोटा कोण x है, तो 2x - 5° का मान क्या होगा?

If the difference between two supplementary angles is 18°, then the smaller angle among them is:

If the complementary angle of an angle is equal to 25% of its supplementary angle, then the angle is:

What is the measure (in degrees) of an angle, if five times its complement is 15° less than twice its supplement?
