2x+3x+x+90=360
6x=270
x=45
Angle A=2x
Angle A=2(45)=90 degrees
So both AD and BC are vertical lines which are parallel to each other.

Answer:
1.411.99Step-by-step explanation:
The Pythagorean theorem (see Hint) tells you the length of the hypotenuse (c) is ...
c² = 1² + 1² = 2
c = √2 ≈ 1.4142136 . . . units
The estimated value of the length of the hypotenuse is 1.41 units.
__
Of course the shaded square will have an area that is the square of that value:
area = s² ≈ 1.41² ≈ 1.99 . . . . . rounded to hundredths
The estimated area of the square is 1.99 square units.
__
Additional comment
Of course, we don't have to estimate. We can use the exact value of the side length to determine the shaded square has an area of ...
area = s² = (√2)² = 2 . . . . exactly
We can also get there by recognizing that the lengths of 1 represent half the length of each of the diagonals of the square. That is, the square's diagonals are both of length 2. The area is half their product, so is (1/2)(2·2) = 2 square units.

Solve the system using elimination
Answers
Answer:
x = 5
y = 1/4
Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are
(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2
-10a - 16b = -66
-20b = - 80
b = 4 5a + 8(4) = 33
5a + 32 = 33
5a = 1
a = 1/5
a = 1/x = 1/(1/5) x = 5
b = 1/y = 4 y = 1/4

How do you do 4 divided by 0.8 in place value
Answers
Answer:
5
Step-by-step explanation:
because that is the correct answer
4 divided by 0.8 is equal to 5.
To divide 4 by 0.8 using place value, you can follow these way
Convert the decimal divisor, 0.8, into a whole number by multiplying both the tip and the divisor by a power of 10.
Since there's only one decimal place in0.8, you can multiply both figures by 10 to exclude the decimal
0.4 x 10 = 40( multiplying the tip by 10)
0.8 x 10 = 8( multiplying the divisor by 10)
Now we've the division problem as 40 divided by 8.
Divide the converted tip by the converted divisor
= 40 ÷ 8
= 5
Thus, 4 divided by 0.8 is equal to 5.

If using the method of completing the square to solve the quadratic equation x2 - 6x – 7 = 0, which number would have to be added to "complete the square"?
Answers
Answer:
(-3)^2
Step-by-step explanation:
You add 7 on both sides, giving you x^2 - 6x = 7
Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7
The answer will be (-3)^2 for this question, but this is not the full solution.
