Step-by-step explanation:

a triangle has 180 degrees in total

so adding the angles altogether we get 180

set the equation up like this

6x + 3 + 75 + 60 = 180

and then combine like terms

6x + 138 = 180

then subtract

6x = 42

and then finally divide

x = 7

Answer:

A) 7

Step-by-step explanation:

180-60=120

120-75= 45

45-3=42

42/6= 7

A) 7
