Answer:
5
Step-by-step explanation:
x + y = 3
xy = 2
x = 1 and y = 2 or x = 2 and y = 1
x + y = 1 + 2 = 3
xy = (1)(2) = 2
y^2 + x^2 = (2)^2 + (1)^2 = 4 + 1 = 5
Answer:
cosA/cosB = 1
Step-by-step explanation:
We know that cos = Adjacent Side/hypothenuse.
Then Cos(A)= AC/AB = 3/4.24 = 0.707
Cos(B) = BC/AB = 3/4.24 = 0.707
Then cosA/cosB = 0.707/0.707 = 1
Answer:multiplication property of -1
Step-by-step explanation:
because it is muliplying by negatives
135.05 = 50 + 9.45x
85.05 = 9.45x
x = 85.05/9.45
x = 9
