Delvig [45]

Answer:

<h2>It's a right triangle. a = 5.</h2>

Step-by-step explanation:

Look at the picture.

We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

We have:

$a\sqrt3=5\sqrt3$ <em>divide both sides by √3</em>

$a=5$

It's a right triangle.

Do the side lengths 4, 5, and 10 form a triangle? Select the correct answer and reasoning.

scoundrel [369]

Answer:

No, because 5 + 4 isn't greater than 10.

Step-by-step explanation:

Given

$Side\ 1 = 4$

$Side\ 2 = 5$

$Side\ 3 = 10$

Required

Do they form a triangle

To check if they form a triangle or not, we make use of trinagle inequality theorem which states that; for sides a, b and c

$a + b > c$

$a + c > b$

$b + c > a$

So for sides 4, 5 and 10, we have:

$4 + 5 > 10$ --- False

$4 + 10 > 5$

$5 + 10 > 4$

<em>Since the one of the inequalities is false, then the sides do not form a triangle.</em>

What is the exact solution for the equation

Nostrana [21]

Answer:

Option C is correct.

Exact solution of $2^{x+2} = 5^{2x}$ is, $\frac{2\ln 2}{2\ln 5 - \ln 2}$

Step-by-step explanation:

Given the equation: $2^{x+2} = 5^{2x}$

Using logarithmic rules:

$a^x=b^y$ ⇒ $x \ln a =y \ln b$

$\ln x^a = a\ln x$

Given: $2^{x+2} = 5^{2x}$

Taking logarithmic both sides:

$\ln 2^{x+2} = \ln 5^{2x}$

By logarithmic rules;

$(x+2) \ln 2 = (2x) \ln 5$

Using distributive property i.e $a\cdot (b+c) = a\cdot b + a\cdot c$

$x \ln 2 +2 \ln 2 = 2x \ln 5$

Subtract $x \ln 2$ from both sides we get;

$x \ln 2 +2 \ln 2 - x \ln 2= 2x \ln 5 - x \ln 2$

Simplify:

$2 \ln 2= 2x \ln 5 - x \ln 2$

or

$2 \ln 2= x (2\ln 5 - \ln 2)$

Divide both sides by $(2\ln 5 - \ln 2)$ we get;

$\frac{2\ln 2}{2\ln 5 - \ln 2} = x$

Therefore, the exact solution of the given equation is $\frac{2\ln 2}{2\ln 5 - \ln 2}$
