the 2 triangles are similar because of math ( don't remember which theorem or whatever)
so since similar
we have to find the bottom length use right triangle properties a²+b²=c² 14²+5.5²=c² 196+30.25=c² 226.25=c² √226.25=c
ten, we do similarity
the hyptonuse of smaller triangle to base of smaller triangle is √226.25:5.5 since the triangles are similar, that should be equal to the ratio of the hypotonuse of the largger triangle to the base, which is x:√226.25
so x/√226.25=√226.25/5.5 times both sides by √226.25 x=226.25/5.5 x≈41.1363636
the height of screen is 6 less than total 41.13636-6=35.13636
