If AB =CD, CD = 9in, BC = 5x, and AD = 53 in. , find x. 35
7
42
6
None of the other answers are correct

B.

Step-by-step explanation:

AD, the entire segment, is composed of the three segments AB, BC, and CD. In other words:

Since AB=CD, we can substitute:

We know that CD is 9 and BC is 5x. AD is 53. So, substitute:

Solve for x:

The value of x is 7.

Hence, our answer is B.

the square root of what number? if you add that, then someone will probably answer the question.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
