Answer:
I estimate bruh.
Step-by-step explanation:
Use cosine rule,
cos(A)=(b^2+c^2-a^2)/(2bc)
=(10^2+12^2-6^2)/(2*10*12)
=13/15
A=29.926 degrees.................................(A)
cos(B)=(c^2+a^2-b^2)/(2ca)
=(12^2+6^2-10^2)/(2*12*6)
=5/9
B=56.251 degrees.................................(B)
cos(C)=(a^2+b^2-c^2)/(2ab)
=(6^2+10^2-12^2)/(2*6*10)
=-1/15
C=93.823 degrees.................................(C)
Check:29.926+56.251+93.823=180.0 degrees....ok

Answer:
False
Step-by-step explanation:
Given
Required
True or False
The above numeral can be split as follows:
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
In Roman numerals;
Substitute 40 for XL and 4 for IV.
Hence;
<em /><em> is false</em>
