Help me please, Find a, b, and c.

Answer:

a = $6*\sqrt{3}$

b = 12

c = $6\sqrt{2}$

Step-by-step explanation:

Since the triangles are right triangles with 60 and 45 degree angles, their side lengths follow special triangles.

A 45-45-90 right triangle has side lengths $1-1-\sqrt{2}$ .

A 30-60-90 right triangle has side lengths $1 - \sqrt{3} -2$ .

Starting with the top triangle which has a 60 degree angle, its side length 6 corresponds to a side length of 1 in the special triangle. It is 6 times bigger so its remaining sides will be 6 times bigger too.

Side a corresponds to side length $\sqrt{3}$ . Therefore, $a = 6*\sqrt{3}$ .

Side b corresponds to side length 2, b = 2*6 = 12.

The bottom triangle has a 45 degree angle, its side length b= 12 corresponds to $\sqrt{2}$ . This means $\sqrt{2}$ was multiplied by $12 = \sqrt{2} * \sqrt{72}$ . This means that side c is $\sqrt{72}=6\sqrt{2}$ .

HELP!!!! Choose the correct answer. Which expression, when evaluated,

blagie [28]

We will check each options and verify it

(a)

$18-2m$

we can plug m=2

$18-2\times 2$

$18-4$

$14$

so, this is FALSE

(b)

$7x-\frac{x}{3} >19$

we can plug x=3

$7\times 3-\frac{3}{3} >19$

$21-1 >19$

$20 >19$

so, this is TRUE

(c)

$6x-1>4x+5$

we can plug x=3

$6\times 3-1>4\times 3+5$

$18-1>12+5$

$17>17$

so, this is FALSE

(d)

$2x^2-3x+1$

now, we can plug x=2

$2(2)^2-3(2)+1$

$8-6+1$

$3$

So, this is FALSE

How do you solve negative exponents?

JulsSmile [24]

Negative Exponent Rule:
this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
