Ineed with my math problem- this might be cheating but eh (it is) anyways- my question is: evaluate 3+11t -9u3+11t−9u3, plus, 11, t, minus, 9, u when t=9t=9t, equals, 9 and u=11u=11u, equals, 11. (sorry this is- complicated.)

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

State if the two triangles are congruent. if they are, state how you know?
