Answer:
32.38°
Step-by-step explanation:
In AXYZ, X = 7.7 inches, y = 4.2 inches and z=7.3 inches. Find the measure of Y to
the nearest degree.
We solve using Cosine rule
Y = arc cos( x² + z² - y²/2xz)
x = 7.7 inches
z = 7.3 inches
y = 4.2 inches
Y = arc cos( 7.7² + 7.3² - 4.2²/2 × 7.7 × 7.3)
Y = 32.38°
