Answer & Step-by-step explanation:
2a - b : 2a + b = 1 : 2
2a - b = 1
- Elimination
2a + b = 2
-b - (b) = -1
-2b = -1
b = 0.5
---------------------------------------------------------------------------------
2a + b = 2 Substitution
2a + 0.5 = 2
2a = 1.5
a = 0.75
--------------------------------------------------------------------------------------
a:b
0.75 : 0.5
or
3/4 : 1/2
Hope this helps!!!

Answer:
C
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos37° = 
= 
( multiply both sides by 15 )
15 × cos37° = x , then
x ≈ 12 ( to the nearest integer )
