Answer:
∅ = 30°
Step-by-step explanation:
given data
side 1 = 6 inches
side 2 = inches
to find out
angle opposite the leg that is 6 inches long
solution
we will use pythagoras theorem that is express as
hypotenuse² = perpendicular² + base² .......................1
put here value and we get hypotenuse
hypotenuse² = 6² + ( )²
solve it we get
hypotenuse² = 144
hypotenuse = 12 inches
now we apply here sin∅ that is
sin∅ = ................2
put here value and we get
put here value and we get
sin∅ =
∅ =
solve it we get
∅ = 30°
