Answer:
28
Step-by-step explanation:
a^2=b^2+c^2-2bc\cos A
a

−2bccosA
From reference sheet.
s^2 = 34^2+16^2-2(34)(16)\cos 56
s
2
=34
2
+16
2
−2(34)(16)cos56
Plug in values.
s^2 = 1156+256-2(34)(16)(0.559193)
s
2
=1156+256−2(34)(16)(0.559193)
Square and find cosine.
s^2 = 1156+256-608.40188
s
2
=1156+256−608.40188
Multiply.
s^2 = 803.59812
s
2
=803.59812
Add.
s=\sqrt{803.59812} \approx28.348 \approx28
s=
803.59812
≈28.348≈28
Answer:
tax=$0.18
Step-by-step explanation:
total cost = $2.18
X+y+z=92
y=3x
z=2x-10
subsitute
x+3x+2x-10=92
6x-10=92
add 10 to both sdies
6x=102
divide by 6
x=17
subsitute
y=3x
y=3(17)
y=51
z=2x-10
z=2(17)-10
z=34-10
z=24
x=17
y=51
z=24
the numbers are 17,51,24
If u mean 1x1/5 and etc it would be: 1/5 2/5 3/5 4/5
