One side is -4.
It can also be x + 4.

Turn 16 + 8x + x^2 into standard form —> x^2 + 8x + 16
Note: standard form is ax^2 + bx + c

Use the “foil” method to factor.
(x + 4)(x + 4)
x=-4

Find the value of y in the given triangle

Andre45 [30]

Given:

In the given triangle,

With respect to y, Perpendicular = 10 cm and Base = 8 cm

To find the value of y.

Formula

By Trigonometric Ratio we get,

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

Now,

Putting the values of perpendicular and base we get,

$tan\theta = \frac{10}{8}$

or, $\theta = tan^{-1} (\frac{10}{8})$

or, $\theta = 51.34 ^\circ$

Rounding off to the nearest tenth, we have;

$\theta = 51.3 ^\circ$

Hence,

The value of y is 51.3°.
