Answer:
x= 10
Step-by-step explanation:
The missing angle inside is 60°
They are not similar because BR: DB is 1:2 and KE:YK is 1:3. This is due because of the slope, the slope of KE:YK is 9/3 or 3/9 which is equal to 1:3 and the slope for BR:DB is 2/4 or 4/2 which is how you get the ratio of 1:2.
1 3/5 because 10 can go into 16 once and that leaves you with 6/10 and to simplify youd have to divinde by 2
