Let the hypotenuse <span>of a 30-60-90 triangle = l
</span>So, the leg which faces angel 60 = l sin 60 = (√3)/2 l // and the leg faces angel 30 = l sin 30 = 0.5 l //
∴ the longer leg = (√3)/2 l
∴ The ratio between the longer leg and hypotenuse = (√3)/2 l : l = (√3)/2 : 1 = √3 : 2 = 3 : 2√3
The correct choices will be C and E

Given the regular octagon shown below, what is the measure of angle x?

vladimir1956 [14]

Answer:

$x=45$ °

Step-by-step explanation:

The angle shown in the figure is known as an external angle.

Also, <u>in a regular polygon (like the regular octagon) the sum of all the exterior angles is the same regardless of the number of sides of the figure</u>:

$360$ °

And to find the measure of a single external angle (such as the angle $x$ shown in the figure) we must <u>divide 360 ° by the number of sides n:</u>

$\frac{360}{n}$

and for the regular octagon, since it has 8 sides:

$n=8$

so the value of x is:

$x=\frac{360}{n}\\ \\x=\frac{360}{8}\\ \\x=45$ °

the measure of angle x is 45° which is the second option

How can you solve an equation that has variables on both sides?

Sindrei [870]

Answer:

After simplifying, the first step in solving an equation with a variable on both sides is to get the variable on one side. This is done by reversing the addition or subtraction of one of the terms with the variable.

Escribe and correct the error in finding the simple interest earned on $500 at 6% for 18 months. I=500(0.06)(18) I = 540

PIT_PIT [208]

Answer: 45$

Step-by-step explanation:

Given

Principal $P=\$500$

Rate $R=6\%$

time $t=18\ \text{months or}\ 1.5\ \text{years}$

Simple interest is given by

$\Rightarrow S.I.=\dfrac{P\times R\times T}{100}$

In the question, time is taken in months which is incorrect

Putting values

$\Rightarrow S.I.=\dfrac{500\times 6\times 1.5}{100}=45\$$
