Answer:
Step-by-step explanation:
a² + b² = (a + b)² - 2ab
The third angle is obtuse.
Since the shape has 3 sides, then the total measure of degrees is (n-2)180 = (3-2)180 = 180°.
So our equation would be
180° = 35° + 30° + x°
x = 115°
115 is greater than 90, so the angle is obtuse.
4n+78n-3/4=942
l
82n - 3/4=942
+3/4 +3/4(.75)
82n=942.75
divide 82 by both sides
n = 11.49 or 11.5
The answer is (108) i hope it works
I believe
