Answer:

≈ 565.5 units²

Step-by-step explanation:

The area (A) of the shaded sector = area of circle × fraction of circle

A = πr² × $\frac{162}{360}$ ← r is the radius

= π × 20² × $\frac{162}{360}$

= 400π × 0.45 ≈ 565.5 units²

Prove that . 1+cot2 theta = cosec2theta

igor_vitrenko [27]

Answer:

see explanation

Step-by-step explanation:

Using the Pythagorean identity

sin²θ + cos²θ = 1 ( divide terms by sin²θ )

$\frac{sin^20}{sin^20}$ + $\frac{cos^20}{sin^20}$ = $\frac{1}{sin^20}$ , that is

1 + cot²θ = cosec²θ ← as required

2×|x|+19=167 find the values of x

Nuetrik [128]

Answer:

x = 74

Step-by-step explanation:

2 * x + 19 = 167

2x + 19 = 167

2x = 148

Divide both sides by 2

x = 74
