Angle g= 180-60-67=120-67=53
so they are similar three angle is the same
PEMDAS
parenthases first
1/4+5/4=6/4=3/2
we now havve
3/2 times 2+ 3/4
multilication
3/2 times 2=6/2=3
now we have
3+3/4=12/4+3/4=15/4
15/4 or 3 and 3/4
Divide each term in
3x=27 by 3.3x3=27/3
Reduce the expression by cancelling the common factors.
Cancel the common factor.
3x3=27/3
Divide
x by 1.x =27 /3
Divide
27 by 3.x=9
Divide each term by 3 and simplify. hope this helps :)
