Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_
18 = r * 130 * pi / 180
18 = 2.269 r
r = 7.93 cm to neraest hundredth
Answer:
34
Step-by-step explanation:
Since AD is a straight line the sum of ABC and DBC would be equal to 180°
2x + 4 + 3x + 6 = 180 add like terms
5x + 10 = 180 subtract 10 from both sides
5x = 170 divide both sides by 5
x = 34
