How do you solve this can you put it in steps

Ok so all the angles in any triangle always add up to 180 degrees.
So we know that in this case one angle is 90 degrees, one is 2x+15 degrees and one is x degrees.
90+2x+15+x=180.
Solve for x.
90+3x+15=180.
105+3x=180.
3x=75
x=25

2(25)+15=50+15=65.

So one angle is 65 degrees, one is 25 degrees and one is 90 degrees

0.04 Pounds. (Lb)

Step-by-Step:

first write an equation

3/5 divided by x

3/5/x

This equation will be 3/5 divided by 15

This then equals 0.04
