If two complementary angles are in the ratio 5:13 then what is the larger angle?

यदि दो पूरक कोणों का अनुपात 5:13 है तो बड़ा कोण कितना होगा?

A 55° / 55° B 60° / 60° C 65° / 65° D 70° / 70°
Show answer and explanation
Correct Answer

C. 65° / 65°

Explanation

The 18 parts equal 90° so one part is 5° and the larger angle is 13 × 5° = 65°.

18 भाग 90° के बराबर हैं इसलिए एक भाग 5° और बड़ा कोण 13 × 5° = 65° है।
