The answer is in the following picture, hopes it can help you~
so,
angle DAB = 25° + 35°
= 60°
now,
angle DAB + angle ADC. = 180°
or, 60° + ADC = 180°
or, ADC = 180° - 60°
Therefore, ADC = 120°
therefore, the angles of the PARALLELOGRAM are 60° and 120°.
To figure this out, just multiply .825 by 1000.
0.825 x 1000 = ?
In order to find the slope, you have to use the formula : Δy/Δx.
Here : Δy = -1 and Δx = 2.
Therefore, the slope would be : B. -1/2.
Hope this helps !
