If cot theta= 4/3, find csc theta

Marrrta [24]

Answer: Option d.

Step-by-step explanation:

The trigonometric identity needed is:

$csc^2\theta=cot^2\theta+1$

Knowing that $cot\theta=\frac{4}{3}$ :

Substitute it into $csc^2\theta=cot^2\theta+1$ :

$csc^2\theta=(\frac{4}{3})^2+1$

Simplify the expression:

$csc^2\theta=(\frac{4}{3})^2+1\\\\csc^2\theta=\frac{16}{9}+1\\\\csc^2\theta=\frac{25}{9}$

Solve for $csc\theta$ . Apply square root at both sides of the expression:

$\sqrt{csc^2\theta}=\±\sqrt{\frac{25}{9}}$

$csc\theta=\frac{5}{3}$

Parallelogram Property: opposite sides are congruent<br><br> Solve for x.

boyakko [2]

Answer:

Value of x = 19

Step-by-step explanation:

We know that in a parallelogram opposite sides are congruent.

So, in the given parallelogram side LM ≅ side NO

So, we can write $2x+2=40$

Solving the equation to find value of x

$2x+2=40\\2x=40-2\\2x=38\\x=\frac{38}{2}\\x=19$

So, value of x = 19
