Answer:
Perimeter = 22.809836694575
Step-by-step explanation:
A(-2, 2) ; B(6,2) ; C(0, 8)
Then
The perimeter of ΔABC = AB + BC + AC
= 22.809836694575
Use the Cosine Rule to find this
cos <B = [b^2 - a^2 - c^2] / -2ac
= [ 4^2 - 10^2 - 11^2] / -2*10*11
= 0.93182
so m < B = 21.3 degrees to nearest tenth. Answer
0.76 x 2 = 1.52
1.40 x 2 = 2.80
1.52 + 2.80= 4.32
Answer is 4 dollars and 32 cents
-i
The best way to explain this is to divide 75 by 4 and whatever remainder you have (in this case 3) you make it i^3 which is -i
