A straight line is 180 degrees in measure

The straight line is made up of three angles

--> angle 1

--> angle 2

--> angle with a little square on it

(angle with a little square means it is 90 degrees in measure)

Let's set up an equation

$angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3$

Thus angle 1 is 3 degrees or the second choice

Hope that helps!

How are the two angles below related? A) Drawing not to scale. B) complementary .C) supplementary. D) adjacent. E) vertical

mamaluj [8]

Answer:

Option C) supplementary

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

In this problem

The measure of angles are

60° and 120°

Their sum is equal to

60° + 120°=180°

therefore

The two angles are supplementary

Billy looks through holiday brochure in Spain, Greece,Italy and UK.

Alenkasestr [34]

Answer:

Assuming you want to know there was for UK it was $\frac{3}{8}$

Step-by-step explanation:

Let's add the fractions together

$\frac{1}{3} +\frac{1}{6}+\frac{1}{8\\}\\\frac{8}{24} +\frac{4}{24} +\frac{3}{24} =\frac{15}{24}$

The remainder is the amount in UK so

$\frac{24}{24} -\frac{15}{24} =\frac{9}{24} \\$

Simplified it's $\frac{3}{8}$

Eva is going to invest in an account paying an interest rate of 6.1% compounded continuously. How much would Eva need to invest,

dolphi86 [110]

Answer:

$46,320

Step-by-step explanation:

Given that

The rate of interest is 6.1%

The amount is $71,000

And, the time period is 7 years

We need to find out the invested amount

As we know that

In the compounded continously, the following formula should be used

Amount = Invested amount × e^(rate × time period)

$71,000 = Invested amount × e^(6.1% × 7)

$71,000 = Invested amount × e^0.427

$71,000 = Invested amount × 1.5326

So, the investment amount is

= $71,000 ÷ 1.5326

= $46324,912

= $46,320
