Angle DAC = 180-25 = 155 degrees
Angle ABC = 180 - 146 = 34 degrees
Angle ADC = 180 - 149 = 31 degrees
ABCD is a quadrilateral and angles in quadrilateral add up to 360 degrees
Angle BCD = 360 - (155 + 34 + 31)
= 360 - 220
= 140 degrees
Do you have the answers like A,B,C,D?
Answer:
b
Step-by-step explanation:
-2
y2-y1/x2-x1
take the y coordinate of the second pair of coordinates and subtract it by the y coordinate of the first pair, then take the x coordinate from the second pair of coordinates and subtract it from the x coordinate from the first pair. then put your answer from the y coordinate over the answer from the x coordinates. 1 - 13 / 8 - 2, then you get -12/6, which simplifies to 2.
Hope this helps :)
