Step-by-step explanation:
Answer: k=225/2
Decimal form: k= 112.5
Mixed number form: k=112 1/2
The square. The square's area is 5x5, which is 25. The circle's is 5*pi/3.14.
Answer:
x = 10
Step-by-step explanation:
Find x by isolating the variable, meaning get rid of every term until the variable, in this case it's x, is on one side of the equation and everything else is on the other side.
x - 2 = 8
Add +2 to both sides of the equation to cancel out the -2
x - 2 = 8
<u> +2 +2</u>
x + 0 = 10
x = 10
Answer:
The value of
is
.
Step-by-step explanation:
The figure provided to is a rectangle, named ABDC.
All the angles, m∠CAB = m∠ABD= m∠BDC = m∠DCA =
.
The lines AD and BC are diagonals of the rectangle ABDC.
According to the diagonal property of rectangles, they bisect each other.
Then,
- m∠CED = m∠AEB and m∠BED = m∠AEC
- AE = BE, CE = ED
- The opposite angle at the points where the diagonals meet are congruent, i.e. m∠DAB = m∠ADC and m∠DCB = m∠ABC.
Now, consider the triangle CED.
Since the triangle CED has two equal sides, i.e. CE = ED, it is an isosceles triangle. And hence the angles m∠DCE = m∠EDC =
(say).
Compute the value of m∠DCE and m∠EDC using the sum of angles property of a triangle i.e. the sum of all three angles of a triangle is
.
Solve for
as follows:
m∠CED + m∠ECD + m∠EDC = 
+
+
= 

So, m∠EDC =
= m∠ADC.
As the opposite angles at the points where the diagonals meet are congruent, then,
m∠DAB = m∠ADC =
.
Thus, the value of
is
.
