Answer:
319
Step-by-step explanation:
\text{Area of a Triangle}\rightarrow \text{S.A.S.}
Area of a Triangle→S.A.S.
\text{Area}=\frac{1}{2}ab\sin C
Area=
2
1
absinC
From reference sheet.
\text{Area}=\frac{1}{2}(12)(55)\sin 75
Area=
2
1
(12)(55)sin75
Plug in values.
\text{Area}\approx318.756\approx 319
Area≈318.756≈31

Answer:
13
Step-by-step explanation:
4+(-3)-2*(-6)
Let us start from the left
2*(-6)= 2 times 6 , where we will have a negative sign on the result as + when multiplied by - gives - (negative)
2*(-6)=-12
4+(-3)-2*(-6) = 4+(-3)-(-12)
Now we open the bracket from the left. It the sign outside the bracket is negative the sign in the bracket will be changed
Hence
4+(-3)-(-12)= 4-3+12
Now -3 +12 we find the difference as the signs are opposite and then place the sign with the larger number
Hence -3+12=9
4-3+12=4+9 = 13
