b) x = 10
Step-by-step explanation:
I hope I helped you^_^
15=|2x-3|
then you take the absolute value sign away
(1) 15=2x-3
and
(2) -15=2x-3
you have a negative 15 because it is the absolute value then you solve for both equations
and get
(1) x= 9
(2) x= -6
Answer:
Step-by-step explanation:
It is given that in △ABC, ∠ABC=90°, BH is an altitude and AB=9 and AC=12, thus using the Pythagoras theorem in △ABC, we get
Now, From ΔABC and ΔHBC, we have
∠ABC=∠BHC(each90)
∠ACB=∠HCB (Common)
By AA similarity, ΔABC is similar to ΔHBC.
Thus, using the similarity condition, we get
