Answer:
<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>
The given shape is known as Trapezium or Trapezoid.
Area of trapezium = ½(Sum of parallel dides) × Height
Area = ½ (3 + 6) × 4
Area = (3 + 6) × 2
Area = 9 × 2
Area = 18 m²
Answer: x=−2
Step-by-step explanation:
x^3+2x^2+3x+6=0
(x+2)(x^2+3)=0
x+2=0 or x^2+3=0
x=−2
Answer:
Here,
(cosθ + sinθ/sinθ) – (cosθ – sinθ/cosθ) = secθ cscθ
Now, Cross Multiplication
(cosθ + sinθ/sinθ) – (cosθ – sinθ/cosθ) = secθ cscθ
cosθ(cosθ + sinθ) – sinθ(cosθ – sinθ)/sinθ cosθ
cos²θ + sinθ cosθ – sinθ cosθ + sin²θ/sinθ cosθ
cos²θ + sin²θ/sinθ cosθ
Here, we know the identity
cos²θ + sin²θ = 1
So,
cos²θ + sin²θ/sinθ cosθ can be written as
1/sinθ cosθ
Here, we also know the identity
1/sinθ = cscθ
1/cosθ = secθ
1/sinθ cosθ can be written as
secθ cscθ
= L.H.S
Hence Proved!!
