What is the length to one side of this triangle

1 answer:

4 0

The formula of the altitude of an equilateral triangle with side x:
$h=\dfrac{x\sqrt3}{2}$
We have:
$h=6\sqrt3$
Substitute:
$\dfrac{x\sqrt3}{2}=6\sqrt3\ \ \ |\cdot2\\\\x\sqrt3=12\sqrt3\ \ \ |:\sqrt3\\\\x=12$

Answer:

x = 15°

Step-by-step explanation:

Complementary angles are two angles whose sum = 90°

∠A + ∠B = 90°

3x + 45 = 90

3x = 45

x = 45/3

x = 15°

lesya692 [45]

Answer:

The answer is "3.14".

Step-by-step explanation:

The coefficient of pollution level is "b" and "a" intercept

$\to y=a+bx\\\\$

We must verify it.

$H_0 :\beta = 0\\\\H_a : \beta \neq 0\\\\$

$Beta \to b=1.76, SE=0.56 \ Estimate$

The statistics on tets are now provided

$\to t=\frac{b}{SE}=\frac{1.76}{0.56}=3.14$

Because statistics will be more than critical $(1.984)$ values, we thus reject $H_0$
