solve this exercise using the fact that the sum of the measures of the three angles of a triangle is 180 degrees.
In a triangle, the measures of the three angles are x, x-29, and x+35. what is the measure of each angle?
~~~~~~~~~~~~~~~~~~~~~~
Write equation as instructed
x + (x-29) + (x+35) = 180.
+-----------------------------------------+
| For it, you should not think. |
| You simply should do as instructed. |
+-----------------------------------------+
Now you should solve this equation.
For it, you rewrite it, moving the constant terms from the left side to the right side, changing the signs to opposite
x + x + x = 180 + 29 - 35
or
3x = 174
x = 174/3 = 58.
So, one angle is 58 degrees; second angle is 58-29 = 29 degrees and third angle is 58+35 = 93 degrees.
ANSWER. The angles are 58 degrees; 29 degrees and 93 degrees.
Solved.
-----------------
This problem is EXTREMELY simple.
What difficult did you find in it, that forced you to write to the forum and ask for help ?
