Answer:
The price before increase = 1255.5
Step-by-step explanation:
7% of 1350 = ![\frac{7*1350}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B7%2A1350%7D%7B100%7D)
= 94.5
The price before increase = 1350 - 94.5
The price before increase = 1255.5
Haha lol 19 copycats left
Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
Answer:
Supplementary
Step-by-step explanation:
∠ADW = 60 +90 = 150°
∠ADW + ∠YDW = 150 + 30 = 180°
If sum of two angles is 180, then they are supplementary
