Step-by-step explanation:
All the sides of the triangle are equal
Therefore, it is a equilateral triangle
and all angles measure 60°.
So, 25x-15= 60
25x = 60+15= 75
x= 75/25
x= 3
2y = 60
y=30
optionA
Answer:
The price was dropped around 15%
Step-by-step explanation:
You will pay $3.15 for a item with original price of $3.70 when discounted 15%. In this example, if you buy an item at $3.70 with 15% discount, you will pay 3.70 - 0.555 = 3.15 dollars.
Answer:
As shown in picture,
Angle CDF = Angle BDE = 54 deg (pair of opposite angles)
Angle CDB = 180 - CDF = 180 - 54 = 126 deg (BF is a diameter).
=> Arc CB = Angle CDB = 126 deg (property of angle on circle)
Hope this helps!

Substitute everything in first
3(-2)-1-3(-2)
Then simplify
-6-1+6 = -1
The answer is -1
