Mathematics
1 answer:
siniylev [52]3 years ago

Answer:

16

Step-by-step explanation:

because V is the midpoint of UW, UV=VW

so 2(UV)= UW

plugging in values to find x,

2(x+6)=9x-2

distribute 2

2x+12=9x-2

7x=14

x=2

finding UW

plug x=2 into 9x-2

UW=9(2)-2=18-2=16

Find the side length of X
7nadin3 [17]

Answer:

7√3

Step-by-step explanation:

We can use pythagoreans theorem to solve this

Since, we know one side, and the hypotenuse, we can solve for the other side.  

Pythagoreans theorem: a²+b²=c²

Where a and b are two sides, and c is the hypotenuse (the side opposite of the right angle)

In this triangle, 7 is the side, and 14 is the hypotenuse.

I will plug in the values into pythagoreans theorem, and then simplify:

a^{2}+b^{2} =c^{2} \\\\7^{2} +x^{2} =14^{2} \\\\49+x^{2} =196\\\\x^{2} =147\\\\x=\sqrt{147} \\\\x=\sqrt{49*3 }\\\\ x=\sqrt{7^{2} *3 }\\\\x=7\sqrt{3}

So x = 7√3
