Step-by-step explanation:
7, HT=
=17 cm
8, S = 1/2.AC.BC.sinC≈28,01 cm^2
9, S =1/2.SR.RT.sin R≈ 3615,7 m^2
Prove:
the area of the ABC triangles is S
sin A = BH/AB
S = 1/2 BH.AC=1/2 sinA.AB.AC=1/2*c*b*sinA
Answer:
Plan A is $3 cheaper can Plan B.
Step-by-step explanation:
first equation: 1.5t+9
second equation: .50t+38
Then substiute the 26 for x. So you get 48 for Plan A and 51 for Plan B. Then subtract so you can get 3, for Plan A is three dollars cheaper than Plan B.

Answer:
angle KPN=95 degree
Step-by-step explanation:
angle KPN = angle JPO (because they are vertically opposite angles)
Now,
angle JPO+angle LOP=180 degree(being co interior angles)
angle JPO + 85 =180
angle JPO =180-85
angle JPO =95
since angle JPO is equal to KPN ,angle KPN is 95 degree
