Answer:
Step-by-step explanation: First figure what’s in the parentheses. (3-2*2) wanna do 2*2 That’s 4 then (3-4) = -1. 2+(-1)*1. Then multiply -1 by 1 which is -1. Then 2+(-1)= 1
4,4,4,5,5,5,6,6,7,8,8,8,9,10,10,10,10
It is the number 7.
The exact values of the remaining <u>five</u> trigonometric functions of theta are
- sinθ = √3/2
- cosecθ = 2/√3
- cosθ = -1/2
- secθ = -2
- cotθ = -1/√3
Since tanθ = -√3.
The remaining <u>five</u> trigonometric functions of theta are sinθ, cosecθ, cosθ, secθ and cotθ.
The next trigonometric function of θ is cotθ.
cotθ = 1/tanθ
= 1/-√3
= -1/√3.
Also, tan²θ + 1 = sec²θ
Substituting tanθ = -√3 into the equation, we have
(-√3)² + 1 = sec²θ
3 + 1 = sec²θ
sec²θ = 4
secθ = ±√4
secθ = ±2
Since θ is in the quadrant II,
secθ = -2
Also, cosθ = 1/secθ
= 1/-2
= -1/2
Also, cot²θ + 1 = cosec²θ
Substituting cotθ = -1/√3 into the equation, we have
(-1/√3)² + 1 = cosec²θ
1/3 + 1 = cosec²θ
cosec²θ = 4/3
cosecθ = ±√(4/3)
cosecθ = ±2/√3
Since θ is in the quadrant II,
cosecθ = +2/√3
Also, sinθ = 1/cosecθ
= 1/2/√3
= √3/2
So, the exact values of the remaining <u>five</u> trigonometric functions of theta are
- sinθ = √3/2
- cosecθ = 2/√3
- cosθ = -1/2
- secθ = -2
- cotθ = -1/√3.

If you would like to solve the above problem, you can do this using the following steps:
1.2 miles * 7 days = 1.2 * 7 = 8.4 miles ... Multiply 1.2 by 7.
2.4 miles * 7 days = 2.4 * 7 = 16.8 miles ... Multiply 2.4 by 7.
8.4 miles + 16.8 miles = 25.2 miles ... Add the two products.
The correct result would be A.
Answer:
The only option 3 is correct
Step-by-step explanation:
See the given diagram.
1. ∠ D = ∠ B {Since AB ║ DE and DB is transverse line. So, they are alternate angles.}
So, ∠ D = 43° ≠ 28°
2. Now, ∠ A = ∠ CED {Again they are alternate angles}
⇒ ∠ A = ∠ CED = 180° - ∠ CEF = 180° - 152° = 28° ≠ 43°.
3. Again, ∠ ACD = 180° - ∠ ACB = ∠ A + ∠ B = 28° + 43° = 71°.
4. ∠ BCE = ∠ ACD {Vertically opposite angles}
⇒ ∠ BCE = 71° ≠ 109°
Therefore, the only option 3 is correct. (Answer)
