It might be no solution:
steps-
x=5-y
x+y=15
substitute the x(which is the top problem) into the second one.
(5-y)+y=15
cancel it out
(5-y)+y=15
-5. -5
a negative plus a positive is gonna equal 0
-y+y=15-5
0=10
that is no solution..

Answer:
<h2>
770 dm</h2>
Step-by-step explanation:
1 meter = 10 decimeter. Deci means ten.
77 meters = 770 dm
The correct question in the attached figure
we know that
applying the law of sines
g/sinG=k/sinK
g=3 units
G=30°
k=4 units
K=?
so
g/sinG=k/sinK------> g*sinK=k*sinG-----> sinK=k*sinG/g
sinK=4*sin 30°/3-----> 2/3
K=arc sin(2/3)-------> K=41.81°
case 1)for angle K=41.81°the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+41.81)--------> H=108.19°
h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 108.19°/sin 30°
h=5.70 units
case 2)for angle K=180°-
41.81°---------> K=138.19°
the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+138.19)--------> H=11.81°
h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 11.81°/sin 30°
h=1.2 units
therefore
the answer is the option
