Question

Find it plz with full explaination ​

Answer 1

Answer:

1

Step-by-step explanation:

cot35° = tan55°

so,

2tan55°/tan55°=2/1=2

tan20°=cot70°

so,

cot70°/cot70°=1/1=1

2-1=1

1

Answer 2

Answer:

1

Step-by-step explanation:

2tan55/cot35 - cot70/tan20

2 tan55/tan(90-55) - cot70/cot(90-70)

2(1) - 1=1
