find the missing angles of triangles ​

angle: 71

x = -3

Step-by-step explanation:

step 1: 180-(55+54) = 71

step 2: x+74=71 (subtract 74 from both sides)

step 3: x=-3

step 4: -3+74=71

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

: )

it is 32.5

i hope i could u.
