Given a 30-60-90 triangle whose shortest leg is 3 centimeters what is the length of the hypotenuse

1 answer:

8 0

the lenght of the hypotenuse is determined either by taking into account sin 30, respectively sin60 and/or cos60, respectively cos30.

Sin 30 = cos60=1/2

the opposite line to the 30 degrees angle is (in this case) called "the shortest leg"

Therefore the value of the hypothenuse is 30×2=60mm

Answer:

8.54

Step-by-step explanation:

formula:

$d=\sqrt{(x2-x1)^2 + (y2-y1)^2}$

$d=\sqrt{(-4 - (-7))^2 + (0-(-8))^2}$

$d=\sqrt{3^2 + 8^2}$

$d=\sqrt{9 + 64}$

$d=\sqrt{73}$

d= 8.54

Answer:

See below.

Step-by-step explanation:

$3+x=ax$ (Given)

$x=ax-3$ (Subtracted 3 on both sides)

$x-ax=-3$ (Subtracted ax on both sides)

$x(1-a)=-3$ (Factor out x from x - ax)

$x=-\frac{3}{1-a}$ (Divided 1 - a on both sides)
