Answer:
Step-by-step explanation:
we are given that 1 angle equals 27 and the other two are equal.
180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5
1ST Piece =======> 2x ======> 2 * 3 ft. ======> 6 ft.
2ND =========> 5x =======> 5 * 3 ft. ======> 15 ft.
3RD ==========> 4 Feet =======> 4 ft.
Sum ======> 25 Feet
Equation:
(2x + 5x) + (4) = 25
Let's solve your equation step-by-step.
2x + 5x + 4 = 25
Step 1: Simplify both sides of the equation.
2x + 5x + 4 = 25
(2x + 5x) + (4) = 25 (Combine Like Terms)
7x + 4 = 25
7x + 4 = 25
Step 2: Subtract 4 from both sides.
7x + 4 − 4 = 25 − 4
7x = 21
Step 3: Divide both sides by 7.
7x / 7 = 21 / 7
Answer ========> x = 3
Check:
(2x + 5x) + (4) = 25
2(3) = 6
5(3) = 15
3rd Piece = 4
Sum = 25
6ft. + 15ft. + 4ft = 25
25 = 25
Hope that helps!!!!!!!!!!!!! : )
Answer:
the second answer
Step-by-step explanation:
Answer:

Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example

and

ARE Conjugates.
The conjugate of

is

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be

We can apply the difference of squares for the denominator.

So our denominator will be

So our rationalized fraction will be

Answer:
A. 6x + 12 = 7x - 8.
Step-by-step explanation:
The opposite angles of a parallelogram are equal so its the first choice.
6x + 12 = 7x - 8.
