Answer:
X = [68]°
Step-by-step explanation:
We know that a triangle has 180 degrees in it from the total angle measure formula:
m = 180(n-2)
Where n equals the number of sides a shape has and m is equal to the sum of interior angle measures.
m = 180(3-2)
= 180(1)
= 180
So if we know two of the angle measures, we can add them then subtract that from the total angle measure to get x.
180-(72+40) = 68
TL;DR - Add the known angle measures and subtract them from the total angle measure to get the third missing angle.
Hope this helps :)
Answer:
<h2>x=68</h2>
Basic fact:
<em>angles in a triangle add up to make 180 degrees</em>
Step-by-step explanation:
we know that
72+40+x=180
112+x=180
-112
x=68

Answer:
y= 2/3x - 3
Step-by-step explanation:
I think it's 138 Long by 109.5 more accurate .
92/73 = 1.26
120/100 = 1.2
138/109.5 =1.26
Hence 138 by 109.5 is more proportionate
