Question

pls tell the answer ​

Answer 1

Answer:

12

Step-by-step explanation:

SIN@=1/2

SO @=30°

3COT^2@+3 = 3×(ROOT3)^2 + 3 =9+3=12

Answer 2

Answer:

according to question :-

2sin Φ = 1

sin Φ = 1/2

p/h = 1/2

p (perpendicular) = 1

h (hypotenuse) = 2

using Pythagoras theorem :-

H^2 = p^2 + b^2

2^2 = 1^2 + b^2

4 = 1 + b^2

4-1 = b^2

√3 = b (base)

cot Φ = b/p

cot Φ = √3/1 = √3

now putting the values in question :-

(3 * (√3)^2+ 3)

3*3+3 = 9+3 = 12

so answer is option 'A' = 12

hope you understand plz thank my answer
