answer: the value of x is 7cm

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
