Yes, it is correct or true: <span>If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.</span>
First find x from the Pythagorean theorem a^2 + b^2 = c^2, where c is the hypotenuse.
7^2 + 24^2 = c^2
49 + 576 = c^2
c^2 = 625, so c = 25
Then to figure out y and z you need to use inverse trigonometric functions.
Use arctan(7/24) = y = 16.3 degrees and arctan(24/7) = z = 73.7 degrees.
X is the shorter base.
Y is 4 less than 3 times x.
This means that if x were to be multiplied by 3, y would be short by 4. If put into an equation it would look like this.
Y = 3x -4
Answer:
n>12
Step-by-step explanation:
Answer: Equations (b) and (e) do not have solutions
Step-by-step explanation: b) The x cancels out (-10x + 35) = -10x + 318; 35 = 318???? NO. e) 3(x + 2) + 1 = x + 2(4 + x); 3x + 7 = 3x + 8. The x cancels out again.
The other s can be solved for x.
