7. Use Repeated Reasoning Given the preimage of a triangle with vertices at
adelina 88 [10]

The coordinates of the vertices of the image are L' = (-4, 6), M' = (-5, 1) and  N' = (-7, 3)

<h3>What are the coordinates of the vertices of the image?</h3>

The vertices of the preimage of the triangle are given as:

L = (4, -6)

M = (5, -1)

N = (7, -3)

The rotation is given as: 180 degrees counterclockwise

<h3 />

The rule of this rotation is

(x, y) => (-x, -y)

So, we have:

L' = (-4, 6)

M' = (-5, 1)

N' = (-7, 3)

Hence, the coordinates of the vertices of the image are L' = (-4, 6), M' = (-5, 1) and  N' = (-7, 3)

Suppose a triangle has to size of lint 42 and 35 and the angles between these 2 sides is 120 which equated should you solve to f
Brilliant_brown [7]

Answer:

7\sqrt{91}\ units or 66.78\ units

Step-by-step explanation:

we know that

Applying the law of cosines

c^{2}=a^{2}+b^{2}-2abcos(C)

In this problem we have

a=42\ units, b=35\ units, C=120\°

c is the length of the third side

Substitute

c^{2}=42^{2}+35^{2}-2(42)(35)cos(120\°)

c^{2}=1,764+1,225-2,940cos(120\°)

c^{2}=4,459

c=\sqrt{4,459}\ units

c=7\sqrt{91}\ units or c=66.78\ units
