Answer:
WERES THE GRAPH
Step-by-step explanation:
Answer:
25.4
Step-by-step explanation:
If double of the number 'x' is 50.8, (2x=50.8)
Then the original number must be half of that value, (x=50.8/2)
50.8/2 = 25.4
x/2 - 3 = 7
x/2 = 10
x = 20
so, option D is correct!!
When the length of sides are given, you can use law of cosine to find the angles
Refer to this website for details

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25
