Sagot :

it’s subtraction, so you must subratct 113 by 72, then your answer will be B= 41

so you start with taking 180-113 because that straight line is made up of 2 angles that equal 180, you’ll get 67 then the three angles of a triangle will add up to 180 so you’ll do 67+72=139 and subtract that from 180 to find your missing angle which is 180-139=41 so
