Question

find the value of the unknown in the following figure ​

Answer 1

hope it helps

x=20√3 m

Answer 2

Answer:

20√3m

Step-by-step explanation:

∠ADC=180-60=120 (Linear pair)

∠DAC + ∠DCA + ∠ADC = 180 (Angle Sum Property)

So Angle DAC is 30

Therefore, it is isosceles and length of AD is 40m

sin=opp./hypotenuse

sin60=x/40

√ 3/2=x/40

x=20√3m
