Answer:

The length of other leg of right angled triangle ABC is 14.4 in

Step-by-step explanation:

Given a right triangle that has 30° angle. The leg adjacent to 30° is 25 inches.

we have to find the length of the other leg.

In ΔABC, by trigonometric ratios

\tan \theta=\frac{Perpendicular}{Base}

\tan 30=\frac{AB}{BC}

\frac{1}{\sqrt3}=\frac{AB}{25}

AB=\frac{25}{\sqrt3}=14.433\sim 14.4 in

Hence, the length of other leg of right angled triangle ABC is 14.4 in

Fifteen times the square of a non-zero number is equal to 20 times number.What is the number? Its not 4/3
e-lub [12.9K]
The number is (2√3) / 3

To find the missing number, convert what it says in words to an equation:
15 {x}^{2}  = 20x
Divide both sides by 15:
{x}^{2}  =  \frac{20}{15}   \\  \\  {x}^{2}  =  \frac{4}{3}
Take the square root:
x =  \sqrt{ \frac{4}{3} }  \\  \\ x =  \frac{2}{ \sqrt{3} }  \\  \\ x =  \frac{2 \sqrt{3} }{3}

P - q i believe because
p = total average
q = average of ac
x = average of bd
p - q = x
