C:
6*2 = 2.5c
c = 4.8
b:
Cannot be solved until the measure of one other angle in the X is added.
Answer:
Step-by-step explanation:
The missing length is 13 because,
Lets say the top triangle is A and the bottom triangle is B.
Triangle A gives us the side GF, and Triangle B gives us the sides TU and ST. Since the triangles are similar(as stated in the problem), we can pair 2 sides GF(A) and TU(B) which is 11:22.(one way I usually figure which sides are similar is by first- matching the hypotenuse, then checking which of the remaining two is longer.. if that made any sense). You can see that their relationship is x2 or /2 (In another word, from A to B is multiplication- ex: 11 * 2 is 22, and from B to A is division- ex 22/2 is 11.) Since the missing number is the hypotenuse of triangle A and you know the Hypotenuse of triangle B all you have to do is divide side TS by 2 to get side SF. So the missing side is 13.
Answer: 13
<u>Ratio of two angles are 6:13.</u>
So, let the one angle be 
and another be 
As we know that,
Sum of all interior angles of a quadrilateral = 
So let's sum up the given angles,
Hence,
So, First angle 
Second angle
