Sasha ordered a kite online. When it arrived, the kite was missing the crossbar. What length crossbar does Sasha need to complete the kite? Round to the nearest tenths if necessary.

Approximately inches

Step-by-step explanation:

The crossbar and two given lengths form a right triangle. We know this because we see a right angle marked on the diagram in between the two given sides.

In this case, we have a right triangle with legs of and , and we need to find the hypotenuse. By the Pythagorean Theorem (, where and are the legs and is the hypotenuse), we get:

(Evaluate exponents)

(Combine like terms)

(Take the square root of both sides of the equation to get rid of 's exponent)

The latter solution is an extraneous solution because the side lengths of a triangle cannot be negative. Therefore, the answer is inches. Hope this helps!

because they could drop even lower..

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
