Answer:

  • h = (2/3)√3
  • b = 3√2

Step-by-step explanation:

It is useful to remember the ratios between the side lengths of these special triangles.

  30°-60°-90° ⇒ 1 : √3 : 2

  45°-45°-90° ⇒ 1 : 1 : √2

__

h is the shortest side, and the given length is the intermediate side. This means ...

  h/1 = 2/√3

  h = 2/√3 = (2/3)√3 . . . . . . simplify, rationalize the denominator

__

b is the longest side, and the given length is the short side. This means ...

  b/√2 = 3/1

  b = 3√2 . . . . . multiply by √2

If a/4 = 9/a, then<br> a²=36<br> 4a = 9a<br> a + 4 = 9 + a<br> a - 4 = 9 - a
Anna [14]

Answer:

Option A is correct.

The given expression : \frac{a}{4} = \frac{9}{a} then;

a^2 = 36

Step-by-step explanation:

Given the expression: \frac{a}{4} = \frac{9}{a}

Cross multiplication the given expression following steps are as follow;

  • Multiply  numerator of the left-hand fraction by the denominator of the right-hand fraction
  • Also, Multiply numerator of the right-hand fraction by the denominator of the left-hand fraction.
  • then, set the two products equal to each other.

Using cross multiplication, on the given expression;

\frac{a}{4} = \frac{9}{a}

First multiply the numerator of the left hand fraction(i.e,a ) by the denominator of the right hand fraction (i,e a)

we have;

\frac{a \times a}{4} = 9

Simplify:

\frac{a^2}{4} =9                              [1]

now, multiply numerator of the right-hand fraction( i.e, 9) by the denominator of the left-hand fraction (i.e, 4 ) in [1]

we have;

a^2 = 9\times 4

Simplify:

a^2 = 36

Therefore, the given expression is equal to: a^2 = 36
