An expression to represent a decimal between 1 and 10 multiplied by ten. basically to write larger numbers with less digits.
ex . 100 = 1 x 10^2
ex. 4321= 4.321 x 10^3
1 and 2 are right because one has adjacent. 2 vertical angles. Vertical angles mean the same plane and adjacent means two sides of an X.
It’s 7 over 69 but 420 for a short answer
0.17
Explain: looked it up and also use Symbolab it’s a math calculator
magnitude = sqrt(6^2+4^2)
= sqrt ( 36+16)
=sqrt (52) = 7.2
angle = tan^-1(6/4) = 56 degrees
