Angle BCA = 180 - 100
angle BCA = 80
Isosceles triangle ABC has two congruent angles, A and B
2x + 80 = 180
2x = 100
Angles A and B = 50 or y and z = 50
I think lines AB and DE are supposed to be parallel, so angles y and x are consecutive interior angles (supplementary)
x = 180 - 50 = 130
Answer:
30 dollars
Step-by-step explanation:
20% times 25
0.20 times 25= 5
25 + 5= 30
Answer:
0.9412
Step-by-step explanation:
Ultimately, if you know the length of the arc, and you know the length of the radius, the central angle (in radians) is just how many radii long the arc is. angle=arc lengthradius length=16 feet17 feet≈0.9412.
Answer: I III and IV
Step-by-step explanation:
The line intersects the x axis at (2,0) and the y axis at (0,-4) so the line goes through quadrants 1 3 and 4 so the answer is the middle or the 3rd from top
