Question

SOME BODY PLEEEASE HELP ME WITH THESE I need these completed by tonight PLLEEASEE7. Find the measures of the following to the

nearest tenth of a
degree Lesson 13.1)

Answer 1

Explanation:

7, HT=
`√(8^2 + 15^2)` =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
