The area of sector is given by:
A=θ/360πr²
θ=210°
r=10/2=5 cm
thus the area will be:
A=210/360×π×5²
A=210/360×3.14×5²
A=45.8 cm²

The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)
xz_007 [3.2K]

Answer:

The measure of the sides is 20 cm.

Step-by-step explanation:

Opposite side of a parallelogram:

Opposite sides of a parallelogram are congruent, that is, they have the same measure.

Measures (2x+10) cm and (x+15) cm:

This means that:

2x + 10 = x + 15

2x - x = 15 - 10

x = 5

2x + 10 = 2*5 + 10 = 10 + 10 = 20

The measure of the sides is 20 cm.

Sally has a discount card that reduces the price of her grocery bill in a certain grocery store
ki77a [65]

0.95c

100% minus 5% is 95%, or 0.95. This means Sally only has to pay 0.95 times the grocery bill, or c, which represents 0.95c.
