Answer:
"76°" is the appropriate solution.
Step-by-step explanation:
Please find attachment of the diagram according to the given query.
The given values are:
In ΔDEF,
f = 610 inches
e = 590
∠E = 70°
∠F = ?
By using the law of sines, we get
⇒ ![\frac{Sin E}{e} =\frac{Sin F}{f}](https://tex.z-dn.net/?f=%5Cfrac%7BSin%20E%7D%7Be%7D%20%3D%5Cfrac%7BSin%20%20F%7D%7Bf%7D)
On substituting the values, we get
⇒ ![\frac{Sin70^{\circ}}{590} =\frac{SinF}{610}](https://tex.z-dn.net/?f=%5Cfrac%7BSin70%5E%7B%5Ccirc%7D%7D%7B590%7D%20%3D%5Cfrac%7BSinF%7D%7B610%7D)
On applying cross multiplication, we get
⇒ ![SinF=\frac{610\times Sin 70^{\circ}}{590}](https://tex.z-dn.net/?f=SinF%3D%5Cfrac%7B610%5Ctimes%20Sin%2070%5E%7B%5Ccirc%7D%7D%7B590%7D)
On substituting the values, we get
⇒ ![=\frac{61\times 0.95969262}{59}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B61%5Ctimes%200.95969262%7D%7B59%7D)
⇒ ![=\frac{57.3212499}{59}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B57.3212499%7D%7B59%7D)
⇒ ![=0.971546608](https://tex.z-dn.net/?f=%3D0.971546608)
now,
⇒ ![F=Sin^{-1}(0.971546608)](https://tex.z-dn.net/?f=F%3DSin%5E%7B-1%7D%280.971546608%29)
⇒ ![=76^{\circ}](https://tex.z-dn.net/?f=%3D76%5E%7B%5Ccirc%7D)
The answer is c. 3.6
3.6 + 3 = 6.6 pounds of sugar
6.6-3 = 3.6 pounds of sugar added to the dough. This weight that must be added to the total weight of the dough.
3.6 (new sugar) +21 (original dough weight) = 24.6 (total weight)
6.6/24.6 = 26.8%
Answer:
3x⁵+8x³+5x²-2x+3
Step-by-step explanation:
3x⁵+8x³+5x²-2x+3
Well simply we need to understand how many feet there are in a yard
in this case
1 yard = 3 feet
1 foot = 12 inches
so 12 x 3 = 36
So the total perimeter of her scarf was 36 inches!
so some possible dimentions of her scarf could be 7 inches wide and 11 inches long.
if we check that
7 + 7 + 11 + 11 = 36!
so this is a correct possibility
