The measure of inscribed angle ABC = 4x – 7. The measure of its intercepted arc = 3x + 10.

a)x =

b) measure of angle ABC =

c) measure of arc AC =

X=4.8

ABC=12.2

AC=24.4

Step-by-step explanation:

,2 (4X-7)=3X+10

8X-14=3X+10

X=4.8

ABC=4 (4.8)-7=12.2

AC=3 (4.8)+10=24.4

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

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
