Answer :
because Jill is standing directly under the kite the angle between jack Jill and the kite is 90°
so
a=12 yards
A°=61°
B°=90°
b=?
to find b we have a formula:
a devided by the sinus of A equals b devided by the sinus of B
12÷sin(61°)=b÷sin(90°)
12÷0.8=b÷1
15=b
so
a=12 yards
A°=61°
B°=90°
b=?
to find b we have a formula:
a devided by the sinus of A equals b devided by the sinus of B
12÷sin(61°)=b÷sin(90°)
12÷0.8=b÷1
15=b
