Answer:
a= 3/11
b = 2/11
Step-by-step explanation:
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
The correct answer is the second choice
Answer:
80,000 + 6,000 + 500 + 3
Step-by-step explanation:

86503 = 80,000 + 6,000 + 500 + 3

So it's 8√2 cause you do c=a/h and manipulate the formula for 8/cos45 :)
