The answer is B. Use the trig identity (sin x)^2+(cos x)^2=1. Since cos x=0.3090, sinx=+-\sqrt(1^2-0.3090^2)=+-0.9511. Since 0<x<90, sin x must be positive, so sin x=0.9511. tan x=sin x/cos x=0.9511/0.3090=3.0780.
Answer:64Step-by-step explanation:
Hi! We’re going to use the pythagorean theorem to answer this.
3 + x^2 = 8
subtract 3 from 8
x^2=5
take the square root of both sides
x=sqrt5
We already know that it will be a dashed line because there is no equal sign in the problem.
6y - 3x > 9
6y > 3x + 9
y > 3/6x + 9/6
y > 1/2x + 3/2
<span>And greater then means shaded above the line.
I hope this helped! :)
