Answer:
The measure of the third angle is
Step-by-step explanation:
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
Let
x ---> the measure of the third angle in degrees
The linear equation that represent this situation is
solve for x

Statements Reason
1. Given
2. Division property of equality
" Division property of equality states that if we divide both sides of an equation by the same nonzero number, the equation remains equal".
3. Simplifying
4. Addition property of equality
"Addition property of equality states that if the same number is added to both sides of an equation, then the equality is still true".
5. Simplifying
Therefore, the solution to the equation is x = -3.
Step-by-step explanation:
9=-3+n+2n
9+3=n+2n
12=3n
n=12/3
n=4
Amount invested at 8% is 1800 , and Amount invested in 5% is .
<u>Step-by-step explanation:</u>
Here we have , An executive invests $21,000, some at 8% and the rest at 5% annual interest. If he receives an annual return of $1,590, We need to find how much is invested at each rate . Let's find out:
Let x be amount invested in 8% , So amount invested in 5% will be
$(21,000-x) . According to question , If he receives an annual return of $1,590
