Answer:
∠A=26º
∠B=137º
∠C=17º
Step-by-step explanation:
We can use the Law of Cosines because we have all 3 side lengths.
cosA =
cosA=28^2+12^2-18^2 / 2(28)(12)
cosA=604/672
cos-1(604/672
angle A ≈ 26º
cosB =
cosB=-316/432
cos-1(-316/432
angle B ≈ 137º
26+137=163
180-163=17
angle C ≈ 17º
1 milligram is equal to 0.001 grams. In other words, divide the mass value by 1000.
3/8=x/20
Multiply both sides by 20.
20(3/8) = 60/8 = 15/2 = 7.5
7.5 = x
