Question

Cos 65°/sin 25°- tan 20°/70°-sin90°+tan5°+tan35°+tan60°+tan55°+tan85° evaluate

Answer 1

Answer:

Step-by-step explanation:cos(90-65°)/sin25°-tan(90°-20°)/cot70°+(1)+tan(90-5°)+tan(90-35°)+(√3)+tan55°+tan85°

Sin25°/sin25°-cot70°/cot70°+1+cot55°+cot85°+1.732+tan55°+tan85°

1-1+1+1+1+1.732

4.732
