Answer:
108m
Step-by-step explanation:
Hello, to find the height of the bigger triangle, you take the width of the bigger triangle and divide by the width of the smaller triangle like this:
72/0.8=90
Then, you take 90 and you multiply it by the height of the smaller triangle like this:
1.2 x 90= 108
So the height of the bigger triangle is 108m.
Right angle 90 degrees is always going to be a right angle.
