If you don't include the outlier (50) then it is 79.7
You would use HL to prove they are congruent! To prove of they were triangles you wouldn't use any of those I don't think.
If the price of an item has been reduced by 65%, that means that it used to be 35% higher, and that is the number we have to use in the equation. Here it is:
x - price
35% - how much it got discounted
60 - new price
100% - total percentage
x : 35 = 60 : 100
100x = 60*35 (crossover multiplication)
100x = 2100
x = 2100 / 100
x = 21
The price of the item now is 21$.
Or you can do it this way:
65% of $60 = 0.65 of 60 = 39; 60 - 39 (how much it was discounted) = 21 (the new price)
Answer:
b = 53
c = 53
Step-by-step explanation:
Alright so we already know that b and c are going to have the same angle measures. We can find b by subtracting 180 degrees to 127. Why you may ask? Its because when b and 127 are added together its obvious that it creates a straight line (supplementary angle). This means that two angles will sum up to 180 degrees. We can create an easy equation and solve for b.
127 + b = 180
b = 53 and c = 53
Best of Luck!
