Answer:
One solution: 0x + 0.5y = 0
Step-by-step explanation:
9x + 4y = 36
6x + 2.5y = 24
2 * Eq. 1
18x + 8y = 72
-3 * Eq. 2
-18x - 7.5y = -72
Add the multiples of the equations.
0x + 0.5y = 0
Answer: One solution: 0x + 0.5y = 0
Answer:
22°
Step-by-step explanation:
Since the triangle is right use the sine ratio
sinQ = 
= 
, hence
Q = 
() = 22° ( nearest degree )
Answer:
c) y = 8
Step-by-step explanation:
in a 30-60-90° Δ the ratio of the sides, respectively, is 1: : 2
if the side opposite the 30°∡ is 8 then 'y' is 8 and 'x' is 16
