Answer:
m2 will be 78 because sum of angles in a strt line is 180 hence if m1 is 102 then m2 will be (180-102) i.e.78
To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the measures of the three angles is 
2. The sum of the interior angle of a triangle is 
3. Let's say that the measure of each angle is
multiplied by the ratio. Therefore, you can write the following equation and solve for
:

4. Therefore, the measure of each angle is:

The answer is: 
Answer: -600 and 1600 were invested into the two accounts.
Step-by-step explanation:
x = amount invested in the first account.
y = amount invested in the second account.
You start off with this equation


Subtract both sides by y.

Subsitude 1000 - x for x for the second equation.

Use the distributive property to solve for y.




Subsitude -600 for y in the first equation and solve for x.


-600 and 1600 were invested into the two accounts.
Answer:
A = 8, B = 9 and C = 6.
Step-by-step explanation:
We can create equations to solve this:
6 + A = 14
So A = 8.
A + B = 17
8 + B = 17
B = 9.
C = 29 - (6 + A + B)
= 29 - ( 6 + 8 + 9)
= 29 - 23
= 6.
Only 2 and 4 are divisible by 116 i think
