Answer:

108°

Step-by-step explanation:

The area of a sector is given by the formula ...

A = (1/2)r²θ . . . . . where θ is in radians

Solving for θ, we find ...

θ = 2A/r²

For your given sector, the central angle is ...

θ = 2(30π cm²)/(10 cm)² = 0.6π . . . . radians

π radians is 180°, so the central angle in degrees is ...

θ = (0.6)(180°) = 108°

The central angle measure of the sector is 108°.

Answer:

40°

Step-by-step explanation:

Triangles QRS and QTS are congruent (HL), so the marked angles are also congruent:

3x +2 = 4x -4

6 = x

Then the total angle measure of angle RST is ...

(3x +2) +(4x -4) = 7x -2 = 7(6) -2 = 40 . . . degrees

m∠RST = 40°

6 4/5 divided by 3 2/9

KiRa [710]

It would be: 6 4/5 / 3 2/9
= 34/5 / 29/9
You can re-write it as:
= 34/5 * 9/29
= 306/145

In short, Your Answer would be 306/145

Hope this helps!
