answer

hello : 1.8

step-by-step explanation:

the number is 1.5% of 120 is : ( 1.5×120)/100 = 1.8

answer:

a. 3 inches

step-by-step explanation:

the radius bc and the tangent ab form a right angle, so triangle abc is a right triangle. bc and cd are radii of the same circle, so they are congruent.

a^2 + b^2 = c^2

(bc)^2 + (ab)^2 = (cd + ad)^2

let the radius bc = cd = x.

x^2 + 4^2 = (x + 2)^2

x^2 + 16 = x^2 + 4x + 4

16 = 4x + 4

12 = 4x

x = 3

answer: 3 inches
