Answer:
<h2>
60 cm^2</h2>
Solution,
Let ,
a = 13
b = 13
c= 10
then,
s = a + b + c /2
= 13 + 13 + 10 / 2
= 36/2
= 18
Now,
Area of triangle:
Hope this helps ....
Good luck on your assignment...
Answer:
as i see from the picture, this lecture mainly taught you relationship of the angles in a specific condition
such as
corresponding angles, AB//CD ,
alternate angles, AB//CD ,
interior angles, AB//CD
In my figure, a+b is always equal to 180degree if the X line is straight
a+b=180
imagine there is Y line which is parallel to the X line
c+d=180
a=c, b=d because y line and x line is parallel (corresponding angles,X//Y)
then b+a=180, substitute c as a, b+c=180(interior angles, X//Y)
Step-by-step explanation:
5x + 7 = 42
5x = 42 - 7
5x = 35
x = 35/5
= 7

Hello from MrBillDoesMath
Answer:
See below
Discussion:
Note the Question incorrectly shows (2n^2 +1) ^ 2. It should be (2n + 1) ^2.
So
(2 n + 1) ^2 - (2n +1) =
4n^2 + 4n + 1 - 2n - 1 = ( -1 + 1 = 0)
4n^2 + 4n -2n + (1-1) =
4(X) = 2 (2X)
Key point. The end result of the evaluation is a multiple of 2 so the result is an even integer.
Thank you,
Mr. B
