Answer:
100 Sq Mt = 1135.69 Sq Ft
Step-by-step explanation:
We are required to find how many square feet are in 100 m squared.
1 meter = 3.37 ft
1 metre x 1 meter = 3.37 x 3.37 Sq ft
1 Sq Mt = 11.3569 Sq ft
100 sq Mt = 100 x 11.3569 sq ft
100 sq mt = 1135.69 Sq ft
Hence
100 Sq Mt = 1135.69 Sq Ft
Answer:
θ =
(60° )
Step-by-step explanation:
Using the identity
sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Given
cos²θ - sin²θ = 2 - 5cosθ
cos²θ - (1 - cos²θ) = 2 - 5cosθ
cos²θ - 1 + cos²θ = 2 - 5cosθ
2cos²θ - 1 = 2 - 5cosθ ( subtract 2 - 5cosθ from both sides )
2cos²θ + 5cosθ - 3 = 0 ← in standard form
(cosθ + 3)(2cosθ - 1) = 0 ← in factored form
Equate each factor to zero and solve for θ
cosθ + 3 = 0
cosθ = - 3 ← not possible as - 1 ≤ cosθ ≤ 1
2cosθ - 1 = 0
cosθ =
, so
θ =

) =
( or 60° )
