Answer:
Step-by-step explanation:
Corresponding angles of two parallel lines are always equal. The angle on "top" of corresponds with the angle marked as . Therefore, its measure must also be .
Since these two angles form one side of a line which has 180 degrees, we have the following equation:
Combine like terms:
Subtract 15 from both sides:
Divide both sides by 3:
Answer:12.8
Step-by-step explanation:
4(7.2-4)
4(3.2)
12.8
The largest angle must be the single angle, so there are two angles that are 20 degrees. 20 + 20 is 40, and because the sum of all angles in a triangle is 180 degrees, you must subtract 180 - 40, and you get 140 degrees as the largest angle. Hope this helps!
