You need to find the angle measurements of the triangle.
The angle supplementary to 128 measures (180 - 128 =) 52 degrees.
Using the corresponding and supplementary property because lines m and n are parallel, you know that the highest (in location) angle of the triangle measure 90 degrees.
A triangle's total angle measurements add up to 180 degrees. Subtract the other two known angles from 180. 180 - 52 - 90 = 38. The third (right side) angle of the triangle measures 38 degrees.
Now, using the supplementary angle theorem, you can find angle a, which is supplementary to the third angle on the triangle. 180 - 38 = 142.
Angle a measures 142 degrees.

Answer: 75 students.
Step-by-step explanation:
In the data set we have a total of 10 + 8 + 7 + 5 = 30 students.
of those, 10 want to go to the park, the percentage is:
(10/30)*100% = 33.3%
Then, out of the 225, we can expect that a 33.3% (or 0.333 in decimal form) want to go to the park, this is:
N = 225*0.333% = 74.925
We can roud it up, and get N = 75
So Sally can expect that 75 students want to go to the park
