C=180-A-B=180-67-53=60deg.

by sine rule

b/sinB=a/sinA
b=a/sinA*sinB
=13/sin(67)*sin(53)
= 11.28

c/sinC=a/sinA
c=a/sinA*sinC
=13/sin(67)*sin(60)
= 12.23

Answer:

25.6

Explanation:

t = 2 seconds

h = 8 + 40.8(2) - 16(2)^2

Solve for h by simplifying both sides of the equation, then isolating the variable.

h = 25.6
