Question 314059: Could someone please help me with this word problem?
The second angle of a triangle is 3 times as large as the first. The third angle is 75 degree more than the first. Find the measure of each angle.
You can put this solution on YOUR website! Hello,
Let x represent the first angle and the second angle will be 3x and the third will be x+75. We know every triangle has 180 degrees, right? We can set up the following equation:
x+3x+x+75=180 Combine like terms to get:
5x+75=180 Subtract 75 from both sides to get:
5x=105 Divide each side by 5 to get:
x=21 degrees for the first angle.
Now you can figure out the other two angles.
Make sense?
