Тhe third angle of the triangle = 90 - 60 = 30°

In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse, therefore $y = \frac{8 \sqrt{3} }{2}=4 \sqrt{3}$

$x=8 \sqrt{3} \cdot \cos30^o =8 \sqrt{3} \cdot { \frac{ \sqrt{3} }{2} } =12$

The answer is x = 12, y = 4√3

Answer:

y = 4 $(2)^{x}$

Step-by-step explanation:

For an exponential function in standard form

y = a $(b)^{x}$

To find the values of a and b, use ordered pairs from the table

Using (0, 4 ), then

4 = a $b^{0}$ ( $b^{0}$ = 1 ), so

a = 4

y = 4 $b^{x}$

Using (1, 8 ), then

8 = 4 $b^{1}$ = 4b ( divide both sides by 4 )

2 = b

Thus

y = 4 $(2)^{x}$ ← exponential function

A paper air plane looking polygon with sides of 5 5 and 8 what is the area

VARVARA [1.3K]

If it has 3 sides then it's a triangle.
Using the formula $A= \sqrt{s(s-a)(s-b)(s-c)}$
where $s= \frac{a+b+c}{2}$
and a=5 b=5 c=8

∴ $s= \frac{5+5+8}{2} =9$
$area= \sqrt{9(9-5)(9-5)(9-8)}$
$area= \sqrt{144} = 12units^{2}$
