Step-by-step explanation: When you solve for x you get 2 so when you put that into the equation (2+1) you get 3. You solve for x but solving this equation (x+5) = (x+1) Hope this helps :)
To find the degree of an exterior angle, subtract the larger arc, DE, degree by the smaller arc, BC, and then divide by 2! Which is 35. 118-48/ 2 = 35.
