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
Expression: 2500 + m
Just substitute m with 300 and solve like that.
2500 + 300 = 2800
Answer:
1,4 and 5
9514 1404 393
x = 5
These points have the same x-coordinate, so are on the same vertical line:
