Question

2tan45°+cos45°+sin30°​

Answer 1

Answer:

Question is :- 2tan45°+ cos 45°+sin30°

Answer:-

= 2(1)+1/√2 + 1/2

=2 + (2+√2) / 2√2

=( 4√2 + 2 + √2)/2√2

=(5√2 +2) / 2√2

=(5√2 + 2)(√2) / (2√2)(√2)

=(10 + 2√2) / 4

=(5 + √2) / 2

Therefore the answer of 2tan45°+cos45°+sin30°

is (5 + √2) / 2
