Answer:
x=-17, y=5. (-17, 5).
Step-by-step explanation:
-2x-5y=9
3x+11y=4
---------------
3(-2x-5y)=3(9)
2(3x+11y)=2(4)
---------------------
-6x-15y=27
6x+22y=8
-----------------
7y=35
y=35/7
y=5
3x+11(5)=4
3x+55=4
3x=4-55
3x=-51
x=-51/3
x=-17
Answer:
x = 14.7
Step-by-step explanation:
Use Law of Sines.
7/sin20=x/sin46
cross multiply
7sin46=xsin20
divide both sides by sin20 to isolate x
x = 7sin46/sin20
x = 14.72
