Answer:a is 40 degrees
b is 140 degrees
Step-by-step explanation:
The given polygon has 5 irregular sides. This means that it is an irregular pentagon. The sum of the exterior angles of a polygon is 360 degrees
The exterior angles of the given pentagon are a, 75, 65, 60 and 120. Therefore
a + 75 + 65 + 60 + 120 = 360
a + 320 = 360
Subtracting 320 from both sides of the equation, it becomes
a = 360 - 320 = 40 degrees
The sum of angles on a straight line is 180/degrees. Therefore,
a + b = 180
b = 180 - a = 180 - 40 = 140 degrees
Add 13 to both sides, which leaves you with k=42.
Answer:
The pattern is that each time, 8 is added. The next 2 numbers are 47, 55.
Step-by-step explanation:
7+8=15
15+8=23
23+8=31
31+8=39
39+8=47
47+8=55
Answer:
A. It would become a different atom.
C. Its charge would increase by 1
Step-by-step explanation:
Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
