Okay, so we know the first triangle is an equilateral and the second is an isosceles. (the lines indicate congruence)
To find x, we have to figure out the other triangle's angles.
Since it is equilateral, all its sides are 60 degrees.
All triangles angles add up to 180. 180/3= 60
To find x we subtract the angle beside it by 180 to find the angle's degree.
180-60= 120. x= 120.
Since it is an isosceles, the last two angles are the same.
Subtract the vertex from 180.
180- 120= 60
Divide that by 2. (since there are two angles)
y= 30 Or choice A. <span />
0.06p = 0.72
p = 12
The original price was $12.
Answer: The answer is B.
Step-by-step explanation:
Angle ABC is a straight angle, which is 180 degrees, so you can rule out answers C and D.
For angle EBG, simply count the measures of the angle on the protractor. From the right, you start at 55. You end at 100. Subtract 55 from 100 to get a measure of 45 degrees.
