Answer:

\text{The length of third side is }\sqrt7 units

Step-by-step explanation:

Given that a triangle has two sides of length 2 and 3 and that the angle between these two sides is 60°.

Let b=2 units and c=3 units

we have to find the length of the third side of the triangle.

By law of cosines

a^2=b^2+c^2-2bc\cosA

where A is the angle between the side b and c

a^2=2^2+3^2-2(2)(3)\cos60

a^2=4+9-6=7

a=\pm\sqrt7

Length cannot be negative

∴ a=\sqrt7 units

Option B is correct.

nata0808 [166]

Answer: 4 7/20 gallons

Step-by-step explanation:

Gallons of soup made = 10 3/5

Gallons that was chicken noodle = 6 1/4

The gallons that wasn't chicken noodle will be:

= 10 3/5 - 6 1/4

= 10 12/20 - 6 5/20

= 4 7/20

Therefore, 4 7/20 gallons wasn't chicken noodle.
