Hello!
∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:
∠E + 119 = 180
Now subtract 119 from both sides of the equation:
∠E = 61
We have now proven that ∠E is equal to 61 degrees.
I hope this helps!

So 70 students had bought lunch because 70% of 100 is 70. Now take away 60% of that and you get 42.
Answer:
$ 158.95
Step-by-step explanation:
Reduction = 25% of 199
= 0.25 * 199
= $ 49.75
Price of the tablet after reduction = 199 - 49.75 = $ 149.25
Sales tax = 6.5% of 149.25
= 0.065 * 149.25
= $ 9.70
Total price that he need to pay = 149.25 + 9.70
= $ 158.95
Answer:
17 7/8
Step-by-step explanation:
8 1/8 = 65/8
9 3/4 = 39/4 = 78/8
8 1/8 + 9 3/4
= 65/8 + 78/8
= (65 + 78) / 8
= 143/8
= (17*8 + 7) / 8
= (17*8)/8 + 7/8
= 17 7/8
