Question

Find the value of x. then classify the triangle by its angles

Answer 1

x = 30, and the triangle is scalene because none of its angles are equal. To get this answer first subtract 60 from 180, because all 3 of a triangle's angles must add to equal 180, and we know one is 60 degrees.

180 - 60 = 120

Now we know 3x and x must equal 120, so the best thing to do know is combine them and divide 120 by 4.

4x = 120

x = 30

Answer 2

Remember, a+b+c=180

3x+x+60=180

subtract 180 from 60

make that 3x+x=120

combine like terms

make that 4x=120

x=30

Triangle is Isoceles Acute Triangle
