Answer:
Cos x = 10/15
Step-by-step explanation:
Which equation can be used to find the measure of angle LJK?
in Δ JLK
∠L = 90°
Base = JL = 10 inch
Hypotenuse = JK = 15 inch
Perpendicular = LK
∠LJK = x
Cosx = Base / Hypotenuse
=> Cos x = 10/15
The above equation can be used to find the measure of ∠LJK
x = Cos⁻¹(10/15) = Cos⁻¹(2/3) = 48.2°
