It would be 2,400 i’m pretty certain
Answer:
A. a=25
B. RCA and QBD
C. Angle PBA
Step-by-step explanation:
2a-9+5a+14=180 since they are same side interior they equal 180
combine like terms- 7a+5=180
subtract 5 from each side- 7a=175
divide 7 from each side- a=25

Is this sequence arithmetic, geometric, or neither?
200, 125, 70, 55,...
A. Arithmetic
B. Geometric
☆☆☆☆☆☆☆☆☆☆C. Neither
Step-by-step explanation:
Work out the value of x.
<h3>#12</h3>
<u>The angles are supplementary as same side interior angles, sum to 180°:</u>
- x + x - 26 = 180
- 2x = 206
- x = 103
<h3>#13</h3>
<u>The angles are corresponding, hence congruent:</u>
- 3x - 5 = x + 55
- 3x - x = 55 + 5
- 2x = 60
- x = 30
<h3>#14</h3>
<u>The angles are supplementary as same side interior angles, sum to 180°:</u>
- 2x + 24 + x = 180
- 3x = 180 - 24
- 3x = 156
- x = 52
<h3>#15</h3>
<u>The angles are corresponding, hence congruent:</u>
- 4x - 12 = 3x + 6
- 4x - 3x = 6 + 12
- x = 18
<h3>#16</h3>
<u>Corresponding with the right angle:</u>
- 4x + 12 = 90
- 4x = 78
- x = 19.5
<h3>#17</h3>
<u>Vertical angle of the bottom angle is supplementary with the top angle:</u>
- 2x + 12 + 3x + 23 = 180
- 5x + 35 = 180
- 5x = 145
- x = 49
