Answer:

Step-by-step explanation:
We have been given a graph of similar triangles. We are asked to find the value of x.
Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.

Upon cross multiplying our equation we will get,
Upon distributing 4 we will get,

Let us subtract 12 from both sides of our equation.

Upon dividing both sides of our equation by 4 we will get,
Therefore, the value of x will be 12.
Since 15409-1=15408 and 15408+1=15409, we can write that as one. With 15409-2, we can write the same thing with 15407+2
The principle SQRT of 100 would be 10 because 10*10 is 100
Since there is a 180 degrees in a straight line and we know that the intersection of one angle is 27 degrees we can can say 180 -27 = 153 degrees. So the four angles would be 27, 27 153, 153
