Answer:
1 439 800
Step-by-step explanation:
200 x 80 x 90 - 200
= 16 000 x 90 - 200
= 1 440 000 - 200
= 1 439 800
X=360, because cos ( 90 degrees ) =0
Answer:
no solution
Step-by-step explanation:
x+y = -2
y = x + 2
let's start by isolating the y in both equations so we can compare them
subtract both sides by x to get this for the first equation
y = -2 + x
y = x + 2
this means
-2 + x = x + 2
subtract x from both sides
-2 = 2
this is never possible, so there is no solution
