x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

x = 20

the two may have that, even a breakdown is probably offered

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
