Answer:

4

Step-by-step explanation:

The three angles in a triangle measure 180°. So add the the 2 known angles 70° + 63° = 133. Then subtract it from 180° to get the unknown angle 180 - 133 = 47.

Now that we know the third angle is 47 we find which number that when multiplied by 11 and 3 is added to that number you get 47.

11×4+3 = 47

Therefore l, the answer is 4
