Find a.b.c if one of the angles is 150
Zepler [3.9K]
Triangle has 180 degrees
1 side=180
Then 180-150= 30 degrees
30/2 (for the other two sides)= 15
So, 150 degrees, 15 degrees and 15 degrees.
So it’s probably an isosceles triangle as the two bottom angles are the same number of degrees

Hope this helps :)

3 (x -1) = 5x +3 -2x
Vika [28.1K]

Steps to solve:

3(x - 1) = 5x + 3 - 2x

~Distribute left side

3x - 3 = 5x + 3 - 2x

~Combine like terms

3x - 3 = 3x - 3

~Subtract 3x to both sides

-3 = -3

~Add 3 to both sides

0 = 0

All real numbers are solutions.

Best of Luck!
