Can some one help me with linear systems I have like three topics in that category and I’m having a lot of trouble I would greatly appreciate it if you would like to help me leave you snap, insta or number down please and thank you

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
