8n-20=15+n
n=5
20 less than 8 times a number = 8(n)-20 same as (=) 15 more (+) than a number(n) 15+n
Hi there!
Since the sum of all angles in any triangle always adds up to 180 degrees, we can calculate this and solve for x.
4x + x + x = 180°
6x = 180
180 ÷ 6 = x
x = 30
So, now we know that x is 30°.
Hope this helps!
