  • This was very helpful with understanding the concepts! Thank you so much! Question 1 was inputted wrong. However i tried it and my answers were: 65,60, and 55 degrees. Correct question reads as: In a triangle the measure of the second angle is 5 degrees less than the first. The measure of the third angle is 5 degrees less than twice the second. Find the measure of the three angles. Am I correct? Thanks again! Learning slowly but surely!
