If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
Find out what x equals too
Ten times two is equal to twenty.
53/4•2/6=1 11/12
Because you must turn 5 3/4 into an improper fraction. So 23/4•2/6. Next you are able to cross reduce because 2 goes into 2 and four so now you have 23/2•1/6 now just multiply across. 2•6=12 and 23•1=23 so now you have 23/12 which equals
1 11/12
