Answer:
∠W = 16.3°
Step-by-step explanation:
In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
From that above question, we are given 3 sides and we are to find the angle of one of the sides.
We solve using Cosine rule.
∠W = arc cos (v² + x²﹣w²/2vx)
∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)
∠W = arc cos (0.9599454365)
∠W = 16.27137°
∠W = 16.3°

Answer:
Dulcina's collection has 57 pins
Eva's collection has 25 pins
Step-by-step explanation:
first we are going to represent the relation of pins by means of an equation
d = Dulcina
e = Eva
e + d = 82
and now we represent the relation of the collections of each one
d = e + 32
having the 2 equations we can replace the d by (e + 32) and place it in the other equation
e + d = 82
e + (e + 32) = 82
2e + 32 = 82
2e = 82 - 32
2e = 50
e = 25
Now we replace e with 25 in the second equation and get the value of d
d = e + 32
d = 25 + 32
d = 57
