Answer:
The answer is 63°
Step-by-step explanation:
The lines intersect so opposite angles are congruent.
2(l+w)=P
72 x 2= 144
240 - 144= 96
96/2= 48
your answer would be 48in.
<u>check
</u>2(72+48)= 240
144+96= 240
240=240

Answer:
n=-5
Step-by-step explanation:
Let "n" represent the unknown number.

So, your equation will be:

First, subtract 2 from both sides:

Then, divide both sides by 4:

Therefore, n=-5.
