It's wrong. Although you were on the right track, the answer is 60 with a remainder of 3
Answer:
Formula for area of a parallelogram;
a = bh
where b is the base, and h is the height
Our height is 64.3
Our base is 4.3
Now we multiply them:-
a = bh
a = 4.3 x 64.3
a = 276.49^2 meters
Answer:
10
Step-by-step explanation:

Therefore, the number is 10
Given:
In given Δ RST,
RS = 9, ST = 8 and ∠S = 110°
To find the value of another side RT (s).
Formula
By cosine law we get,

Now,
Putting,
b=9, c=8, A = 110° and a=s we get,

or, 
or, 
or, 
or, 
or, 
Hence,
The value of s is 14. Option C.
