Help me plzzzzzzzzzzzzzzzz ughhhhhhhhhhh

Answer 1

Answer: 60

=====================================================

How to get this answer:

The triangles are similar so the horizontal sides divide to get some ratio R

R = (long horizontal)/(short horizontal)

R = h/45

At the same time, the slanted sides divide in a similar fashion to get the same ratio R

R = (long slanted)/(short slanted)

R = (17+51)/(51)

R = 68/51

------------

Because we have the same R value, we can set the fractions equal to one another. Then we can isolate h

h/45 = 68/51

51*h = 45*68 ... cross multiply

51*h = 3060

51h/51 = 3060/51 ... divide both sides by 51

h = 60
