Answer:
19.20cm
Step-by-step explanation:
Step one:
Given data
the length of the ramp is the same as the hypotheneus= 63cm
the horizontal base is the same as the adjacent= 60cm
the height is the same as the opposite
we can use Pythagoras theorem to solve for the height
Step two:
hyp^2= opp^2+adj^2
63^2=opp^2+60^2
3969=opp^2+3600
3969-3600=opp^2
369=opp^2
square root both sides we have
Opp=√369
Opp=19.20cm
the height is 19.20cm
