Answer:
Step-by-step explanation:
If BD is altitude then AC is the base.
<u>The length of AC is:</u>
<u>The length of BD is:</u>
<u>The area is:</u>
y=4
Answer: PQ=15
XY=(PQ+SR)/2
PQ+SR=2*XY
PQ+35=2*25
PQ+35=50
PQ=15
Expand
8a + 16 + 4 + 6a
Collect like terms
(8a + 6a) + (16 + 4)
Simplify
<u>14a + 20</u>
