Question 248482
The sum of the measures of any triangle is 180 degrees. Find the angle measures of a triangle if:


1.  the second angle measures 10 degrees less than twice the first and 
2.  the third angle measures 25 degrees more than the second


Let x = one angle
Let 2x-10 = second angle
Let (2x-10)+25 = third angle ...same as... 2x+15
Their sum equals 180 degrees


Therefore, the equation becomes: {{{x+(2x-10)+(2x+15)=180}}}


Now add like terms and solve for x to determine the first angle.
Plug this value in 2x-10 to determine the second value.
Plug the x value in 2x+15 to determine the third angle.


They must all add up to 180.  I'll let you take it from here!
