Answer:

<h2><u><em>60° is your answer</em></u></h2>

<u><em></em></u>

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

180 - 70 = 110

110 = 12x + 2 + 15x

108 = 27x

108 : 27 = 4°

4 * 15 = 60° is your answer

check

15 * 4 + 12 * 4 + 2 + 70 = 180

60 + 48 + 72 = 180

the answer is good

grandymaker [24]
There are more atoms in average human body than grains of sand on Earth. We can know it because we can see that atoms' number (7 * 10^27) is being multiplied by much greater number (with 9 zeros more) than grain's number (7.5 * 10^18).

Combine like terms to simplify the expression of -5.55-8.55c+4.35c ​
Rashid [163]

Answer:

-5.55-4.2c

Step-by-step explanation:

-5.55-8.55c+4.35c

-8.55c and 4.35c are like terms so you have to combine them.

-8.55c+4.35c=-4.2c

-5.55 is NOT a like term so it is on its own.

final answer -> -5.55-4.2c

*** don't forget -5.55 is negitive  ***

hope this helped negative:)
