Answer:
x = 50°
Step-by-step explanation:
x + 20° + 30° = 180°
x = 180° - 20° - 30°
x = 130° (This one is other x)
x + 130° = 180°
x = 180° - 130°
x = 50°

Answer:
36m
Step-by-step explanation:
If the area of a square is 81 m
A=81m
but we know that A=l² so l=radA
l=9m
p=4l
finally p=4•9=36m

A linear pair is supplementary.
It always helps to draw out a diagram with the information you have - it makes the solving process more visual and sometimes easier. I have attached a diagram of this linear pair.
So, since a linear pair is supplementary, we know these two angles add to equal 180°. Let's write this in an equation.
(5<em>n</em> + 15) + (4<em>n</em> + 21) = 180
Solve for <em>n</em>.
(5<em>n</em> + 15) + (4<em>n</em> + 21) = 180
5<em>n</em> + 15 + 4<em>n</em> + 21 = 180
9<em>n</em> + 36 = 180
9<em>n</em> = 144
<em>n</em> = 16
We're not done yet - now we have to plug this in for <em>n</em> to find the angle measures.
5<em>n</em> + 15
5(16) + 15
80 + 15
95
4<em>n</em> + 21
4(16) + 21
64 + 21
85
Lastly, check your work by adding the angle measures.
95 + 85 = 180
