Answer 1

Answer:

tan260∘+4cos245∘+3sec230∘+5cos290∘

tan260∘+4cos245∘+3sec230∘+5cos290∘=2+2−(3)2(3)2+4(21)2+3(32)2+5(0)

tan260∘+4cos245∘+3sec230∘+5cos290∘=2+2−(3)2(3)2+4(21)2+3(32)2+5(0)=2+2−33+4(21)+3(34)

tan260∘+4cos245∘+3sec230∘+5cos290∘=2+2−(3)2(3)2+4(21)2+3(32)2+5(0)=2+2−33+4(21)+3(34)=3+4(21)+3(34)

tan260∘+4cos245∘+3sec230∘+5cos290∘=2+2−(3)2(3)2+4(21)2+3(32)2+5(0)=2+2−33+4(21)+3(34)=3+4(21)+3(34)=3+2+4

tan260∘+4cos245∘+3sec230∘+5cos290∘=2+2−(3)2(3)2+4(21)2+3(32)2+5(0)=2+2−33+4(21)+3(34)=3+4(21)+3(34)=3+2+4=9
