Answer:
The proton number is found in the periodic table of elements.
Explanation:
<em>The atomic number </em>is the number that defines each element in the periodic table. It accounts on the number of protons in a nucleus of an element, as well as the number of electrons. It is marked by the letter Z.
It should be distinguished from the mass number which is the total number of protons <em>and </em>neutrons inside a nucleus.

The creative curriculum model claims to be guided by all of the following researchers D. Howard Gardner
1st, let's calculate the side AB = c in applying the law of cosine:
AC² = BC²+AC² - 2AB.BC. cos87°)
c²= 10.1²+9.8²-2(10.1)(9.8)(cos(87)
c²=102.01 + 96.04 -196.96cos(87)
c² = 187.74 and c = 13.7
Having calculated the 3rd side, now we can apply Heron's formula for the area:
AREA = √p(p-a)(p-b)(p-c), where p is half the perimeter or p=(a+b+c)/2 =16.8
AREA = √16.8(16.8-10.1)(16.8-9.8)(16.8-13.7)
AREA = 49.42 OR 49.4 unit²
