Answer: a. area= 35ft² & perimeter= 31ft

b. area= 25in² & perimeter= 18in

Step-by-step explanation:

a. area= 1/2 x base x height Perimeter= 14+7+10

= 1/2 x 10 x 7 = 31ft

= 35ft²

b. area= 1/2 x base x height Perimeter= 25/3 + 13/3 + 16/3

= 1/2 x 25/3 x 6 = 18in

= 25in²

*Mastery Check. DO NOT ask for help. Find the area of the sector. Round your answer to the nearest tenth.

Juliette [100K]

The area of the sector is 472.6 ft²

<h3>Area of a Sector</h3>

For finding the area of the sector, you need apply the formula:

$A=\pi r^2* \frac{\alpha }{360}$ , where:

r= radius

α= central angle

The question gives:

r= radius= 19 ft

α= central angle = 150°

Thus, the area of the sector will be:

$A=\pi r^2* \frac{\alpha }{360}=\pi *19^2*\frac{150}{360} =472.6$

Find the length of RA. A. 42 B. 84 C. 14 D. 7

fiasKO [112]

Answer:

$\large \boxed{\mathrm{B. \ 84}}$

Step-by-step explanation:

$LU$ bisects $RU$ and $UA$ .

$RU=UA$

$3m+21=6m$

Solve for m.

Subtract 3m from both sides.

$21=3m$

Divide both sides by 3.

$7=m$

Calculate $RA$ .

$RA=3m+21+6m$

$RA=9m+21$

Put m = 7.

$RA=9(7)+21$

$RA=63+21$

$RA=84$
