To find the area of this triangle, we may use Heron's formula:
A = sqrt ((s)(s - a)(s - b)(s - c))
where s is the semi - perimeter, a, b, and c are the measure of the sides.
s = (a + b + c) / 2 = (10 + 10 + 16) / 2 = 18
Substituting this to the equation for area,
A = sqrt ((18)(18 - 10)(18 - 10)(18 - 16))
A = 48 units²
I am pretty sure that the 117 represents the number of additional texts per month. To understand why I think so just subtract 237-120 you get 117 or 354-237 and so on which would have the same. So, the correct answer is D. The number of the additional texts per month
Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
