Do 3x-5+x+x=180 since all triangles add up to 180 degrees
Then 5x+5=180
Subtract 5 which give you 5x=175
Divide by 5
And your answer is 35 degrees
Then 3x-5+35=180
3x+30=180
Add the 30 to both sides
And divide by 3 on both sides
The other x is 60
X=60,x=35
Hope this helped

Answer:

x=37

Explanation:

We know that the angles in a triangle must add to 180 degrees

So, the three angles: x, 3x-5 and x must be equal to 180

x+3x-5+x=180

Combine like terms

x+3x+x-5=180

5x-5=180

Add 5 to both sides

5x=185

Divide both sides by 5

x=37
