5+3x=37
Step 1
subtract 5 from both sides
3x=32
Step 2
divide by three
x=10.6(repeating)
10*4230 that should do the trick for ya just multiply it and ya got answer
<span />
The angle between two vectors is:
CosФ = u - v / Magnitude(u) x magnitude(v)
Magnitude of u = SQRT(7^2 + -2^2) = SQRT(49 +4) = SQRT(53)
Magnitude of v = SQRT(-1^2 +2^2) = SQRT(1 +4) = SQRT(5)
u x v = (7 x -1) + (-2 x 2) = -7 + -4 = -11
cosФ = -11 / sqrt(53) x sqrt(5)
cosФ = -11sqrt265) / 265
Ф =cos^-1(-11sqrt265) / 265)
Ф=132.51 degrees.
4(10+3)
40+12
52
Mark brainliest please
Hope this helps you
