Answer:

The exterior angles need to equal 360 degrees.

You have 70 + 65 + 75 = 210

So 2x + 3x need to equal 360 - 210 = 150

5x = 150

x = 150 /5 = 30

2x = 2 *30 = 60

3x = x *30 = 90

An interior angle and an exterior angle need to equal 180 degrees.

The largest interior angle would need to correspond with the smallest exterior angle.

The smallest exterior angle is 2x which equals 60 degrees.

The largest interior angle would be 180 - 60 = 120 degrees.

Answer:

160/196

Step-by-step explanation:

it would be easier if you converted all fractions to improper fractions

so 3 1/5 would equal 16/5 and 2 4/5 would equal to 14/5

$\frac{14}{5} - \frac{2}{3}$ : to solve this you would need the same common denomenator,

to do this you can multiply 5 and 3 by something to make the lowest common denominator, which would be 15

thus

multiplying first fraction by 3 and the second by 5

42/15 - 10/15 = 32/15

now 32/15 divided by 14/5

the rule for dividing fractions, is flipping the fraction which you will be using to divide, and then multiplying it to the first fraction:

$\frac{32}{14}$ multiplied by $\frac{5}{14}$

thus, answer is 160/196

Write down the 5th term in the sequence given by t(n) = n^2 +2n

madam [21]

So it our equation would be t(5)=5^2+2(5)
25+10=35 :)
