Angles that are across from each other are equal, so Z = 66, then you know that when you have a line, it equals 180 degrees, so you do 180-66=15x-6 and solve for x, when you do this, you get 8 as the answer.  
180-66=15x-6
(+6) 114=15x-6 (+6)
(/15) 120=15x (/15)
8=x

How you know that the values of the digit in the numbers 1500,000 and 100,500 ate not the same
Sliva [168]

In this number 1500,000,

1 is at million place and 5 is at hundred thousand place

So, the value of 1 = 1 (1,000,000) = 1 million

And the value of 5  = 5 (100,000 ) = 500,000 = Five hundred thousand

In the second number 100,500

1 is at hundred thousand place and 5 is at hundred place

The value of 1 = 1 (100,000) = 100,000 = Hundred thousand

And the value of 5  = 5 (100 ) = 500 = Five hundred

Since the digits 1 and 5 both are at different places in both the numbers so 1,500,000 and 100,500 are not the same.

What is the solution of square root of x plus twelve equals x
Bess [88]

Answer:

x=4

Step-by-step explanation:

√x+12=x

x+12=x2(Square both sides)

x+12=x2

x+12−x2=x2−x2(Subtract x^2 from both sides)

−x2+x+12=0

(−x−3)(x−4)=0(Factor left side of equation)

−x−3=0 or x−4=0(Set factors equal to 0)

x=−3 or x=4

x=−3(Doesn't work in original equation)

x=√x+12
