Answer:
total ground and wall angle is 90°
beam angle with ground= 51
beam angle with wall =39
because total angle=angle with ground + angle with wall
angle with wall=total angle-angle with ground
angle with wall= 90-51=39
The angle of the triangle would be 72
Either you can use distributive property or you can add up the numbers in the brackets.
Hopefully that helped! :)
In order to find the answer you multiply 1360 by .15 and you get the answer of 204. So 204 students are absent.
