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.

$RA=9(7)+21$

$RA=63+21$

$RA=84$
