Five fourths of a right angle

A right angle is 90 degrees.

Five fourths is $\sf \frac{5}{4}$

Five fourths OF A right triangle

$\sf \frac{5}{4}$ OF 90 degrees

Of means multiplication so:

$\sf \frac{5}{4}\times 90$

And that equals to 112.5

So your final answer is

$\boxed{\bf{112.5~degrees}}$

Louise completed the work shown below.(5x3 3)2 = (5x3)2 (3)2 = 25x6 9determine if louise’s answer is correct. explain.

mestny [16]

Let us first assume that the operator between 5x^3 and 3 is addition. What Louise did was incorrect, as she did not follow the proper way of expanding a binomial. The actual steps to take when taking the square of a binomial is as follows:

(5x^3 + 3)^2 = (5x^3 + 3)(5x^3 + 3)
25x^6 + 15x^3 + 15x^3 + 9
25x^6 + 30x^3 + 9

The actual answer is 25x^6 + 30x^3 + 9.

Scorpion4ik [409]

Answer:

464 feet

Step-by-step explanation:

The Sine of the angle of inclination gives the increase in altitude.

This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e

Sin Ф = Opposite ÷ Hypotenuse

Sin 5° = O ÷ 5328
