2. one angle of and one side are equal therefore bc and ce have to equal each other.
3.because angle a and angle d equal each other, angles acb and dce equal each other
4.opposite interior angles equal each other
5.triangles equal each other for all the reasons above
Answer:
the first one :)
Step-by-step explanation
If the number of negatives is an even number it would make it positive and if it is an odd number it would make it negative.

Answer:
555.94
Step-by-step explanation:
16 x 11 = 176/2
88
since there are two of the same triangle
88 x 2
176
11 is the radius
A =
A = 3.14 ( pie is 3.14, if not then pi) x (11x11)
A = 3.14 x 121 (or 121)
A = 379.94
379.94 + 176 (or 121pi + 176)
555.94

Answer: 35 (choice C)</h3>
=============================================
Explanation:
For any triangle, the three interior angles always add to 180.
D+E+F = 180
(7b+1) + (2b+1) + (b+8) = 180
(7b+2b+b) + (1+1+8) = 180
10b+10 = 180
10b = 180-10
10b = 170
b = 170/10
b = 17
Use this value of b to find the three angle measures
- D = 7b+1 = 7*17+1 = 119+1 = 120
- E = 2b+1 = 2*17+1 = 34+1 = 35 degrees
- F = b+8 = 17+8 = 25
As a check,
D+E+F = 120+35+25 = 120+60 = 180
which helps confirm the correct answers.
