Answer:
95 degrees
Step-by-step explanation:
The given shape is a triangle.
Let the missing angle be " x ".
Sum of interior angles in a triangle is 180 degrees,
x + 45 + 40 = 180
x + 85 = 180
Subtract 85 on both sides,
x = 180 - 85
x = 95 degrees
<u><em>95°</em></u> (b)
the sum of the interior angle of a triangle is 180°
so
180 - 40 - 45 =
95°
B
Because 9 = 5 +4
