Answer:

103 degrees

Step-by-step explanation:

The angles in a triangle always add up to 180 degrees

so 62+15=77

180-77=103

hope it helps :)

Answer:

103º

Step-by-step explanation:

All angles of a triangle add up to 180º

This means:

62º + 15º + the third angle = 180º

Then you just solve:

180º - 77º = 103º

Hope this helps :)

Wich expression best estimates - 18 1/4 divided by 2 2/3
yKpoI14uk [10]

-18/3

18/(-3)

<h2>Explanation:</h2>

The complete question is as follows:

________________________________________________

Which expression best estimates -18 1/4 divided by 2 2/3?

18/3

-18/3

-18/(-3)

18/(-3)

________________________________________________

So in this exercise, we have two mixed fractions. This type of fractions comes from the combination of a whole number and a proper fraction fraction (numerator less than denominator). In order to solve this problem, we need to transform these mixed fractions into improper fractions (numerator greater than denominator). So:

-18 \frac{1}{4}=-\left(18+\frac{1}{4}\right) \\ \\ Cross \ Multiplication\  -\left(\frac{18\times4+1}{4}\right) \\ \\ Solving \ numerator \ -\frac{72+1}{4} \\ \\ Simplifying \ -\frac{73}{4}

2 \frac{2}{3}=2+\frac{2}{3} \\ \\ Cross \ Multiplication\  \frac{2\times 3+2}{3} \\ \\ Solving \ numerator \ \frac{6+2}{3} \\ \\ Simplifying \ \frac{8}{3}

By dividing:

\frac{-\frac{73}{4}}{\frac{8}{3}} \\ \\ It's \ the \ same \ as: \\ \\ -\frac{73\times 3}{8\times 4}=-\frac{219}{32} \approx -6.84

<em>So the expressions that best estimates -18 1/4 divided by 2 2/3 are:</em>

<em>-18/3 </em>

<em>18/(-3)</em>

<em>Whose value in decimal form is -6.0</em>

Answer quick for brainliest
andre [41]

Answer:

$40 in interest and $240 in total

Step-by-step explanation:

find 5% of 200: 200 x 0.05=10

it's for four years, so multiply times four: 10x4=40

that's the amount of interest so now add that to her original 200 and you get 240!
