Answer:

DG=8.62

Step-by-step explanation:

DG is also the hypotenuse. Use the sine ratio. Insert values:

sineX=\frac{opposite}{hypotenuse}\\\\sin72=\frac{8.2}{x}

Solve for x. Multiply both sides by x:

x*(sin72)=x*(\frac{8.2}{x} )

x*sin72=8.2

Divide both sides by sin 72:

\frac{x*sin72}{sin72}=\frac{8.2}{sin72}

x=\frac{8.2}{sin72}

Insert into a calculator:

x=8.622

Round to the nearest hundredth:

x=8.62

Done.

Find the value of 5.8 divided by 1.2
Katena32 [7]
It is easier to do if we get rid of the decimals, so lets multiply both numbers by 10:
5.8/1.2 = 58/12
and reduce the fraction:
= 29/6
then operate:
= 4.83

In the year 2003, a company made $6.8 million in profit. For each consecutive year after that, their profit increased by 13%. Ho
LenKa [72]

Answer:

$7.7 million

Step-by-step explanation:

Given: $6.8 million profit made by company.

           13% increase in profit every year.

Now, finding the company´s profit in the year of 2006.

As we know there is 13% increase in profit.

∴ Profit increase= \frac{13}{100} \times 6.8= \$ 0.884

Next adding company´s profit with increase in profit to get profit in the year 2006.

∴ 6.8+0.884= \$ 7.684 ≅ $7.7

The company´s profit in the year 2006 is $7.7 million.

Help how do I solve it
Mila [183]
When two lines intersect, opposite angles are equal. This means that angle 1 equals angle 4. We can use that information to find their values.
Angle 1 = Angle 4
6n+1 = 4n+19
2n=18
n=9

6(9)+1=54+1=55

Angle 1 and 4 equal 55 degrees.

Two angles that form a straight line together have a total sum of 180 degrees. Angles 1 and 5 are like this, as well as Angles 4 and 5, and Angles 4, 3, and 2 added together.

Therefore, 180 = (angle 4) + (angle 3) + (angle 2)
180= 55+(angle 3) + (angle 2)
125= angle 3 + angle 2

I'm not sure what else can be extrapolated from this. There doesn't seem to be a way to find out what the measure of angle 2 is without angle 3 as well. I hope this helps and you can figure it out from the answer choices!
