Answer:

The median is marked at 161cm instead of 162cm.

The right part of the box (the upper quartile) is marked at 172cm, while the interquartile range is 17cm, so the upper quartile should be at 154cm + 17cm = 171cm.

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
