Since we know that length is twice the width, we can say that:
Perimiter = 2(twice the width) + 2(width)
Therefore, P = 2(2w) +2(w)
this simplifies to P=6w
Sine P=180, 160 = 6w, so w = 30
Because length is twice the width, length = 2 * width, or 2*30, which is 60

Therefore:
length = 60
width = 30

Line AC is tangent to circle O at point C<br> What is the measure of OAC?
Nuetrik [128]
AC is a tangent so by definition, it touches the circle at exactly one point (point C) and forms a right angle at the tangency point. So angle ACO is 90 degrees

The remaining angle OAC must be 45 degrees because we need to have all three angles add to 180
45+45+90 = 90+90 = 180

Alternatively you can solve algebraically like so
(angle OAC) + (angle OCA) + (angle COA) = 180
(angle OAC) + (90 degrees) + (45 degrees) = 180
(angle OAC) + 90+45 = 180
(angle OAC) + 135 = 180
(angle OAC) + 135 - 135 = 180 - 135
angle OAC = 45 degrees

Side Note: Triangle OCA is an isosceles right triangle. It is of the template 45-45-90.

kherson [118]
\bf (3x+4)^2=14\implies \sqrt{(3x+4)^2}=\pm\sqrt{14}\implies 3x+4=\pm\sqrt{14}&#10;\\\\\\&#10;3x=\pm \sqrt{14}-4\implies x=\cfrac{\pm \sqrt{14}-4}{3}\implies x=&#10;\begin{cases}&#10;\cfrac{\sqrt{14}-4}{3}\\\\&#10;\cfrac{- \sqrt{14}-4}{3}&#10;\end{cases}
