Answer:

AB ≈ 5.6 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos62° = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{BC}$ = $\frac{AB}{12}$ ( multiply both sides by 12 )

12 × cos62° = AB , then

AB ≈ 5.6 cm ( to 1 dec. place )

Use the Law of Sines. Find the indicated measure to the nearest tenth. In Triangle RST, m∠R =78, m∠T =39, and TS with line on to

vovikov84 [41]

Answer:

RS = 12.2 in ⇒ answer (a)

Step-by-step explanation:

∵ m∠R = 78° , m∠T = 39° , TS = 19

∵ By using sin Rule:

∵ ST/sin∠R = RS/sin∠T

∴ 19/sin78 = RS/sin39

∴ RS = (19 × sin39) ÷ sin 78 = 12.2 in ⇒ answer (a)
