Option C:
A triangle that does not have the same dimension as one of the sides of pyramid.
Because....
There is a rectangular Pyramid, which is sliced perpendicular to its base and through its vertex.
Answer:
x = 5
Step-by-step explanation:
Here, we are interested in calculating the value of x.
We can obtain this from the given angle in the question.
Mathematically;
<CDE = <YDE + <CDY
Thus;
147 = 10x-3 + 21x-5
147 = 31x -8
31x = 8 + 147
31x = 155
x = 155/31
x = 5
Assuming that there are plus signs between the 6, 2, and 9 the answer is 21x+20
Consecutive integers have similar characteristics in such a way that their difference is their differences is always one. For example, 1,2,3...
the difference between the consecutive integers is 1. therefore if the first integer is n, the next one will be:
n, (n+1),(n+1+1),...
this will give us:
n,n+1, n+2,......
the answer is:
1. n, n+1, n+2,.....
Multiply the 8 by each term to get 8x -24
The answer is A. 8x-24
