I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
Answer:
Angle A = 180
Step-by-step explanation:
180=7x+40
Subtract 40 from both sides
140 = 7x
Divide 7 from both sides
20=x
Substitue 20 in for x
7(20)+40
140+40 = 180
