Answer:
D
Step-by-step explanation:
We are given that a triangle LKJ
LJ=8.9 cm
KJ=10.9 cm
[tex]\angle LKJ=x[/tex]
We have to find the measure of angle LKJ
To find the value of angle LKJ we will use Sin x
[tex]Sin x=\frac{Perpendicular\;side}{Hypotenuse}[/tex]
Substitute the values then we get
[tex]Sin x=\frac{8.9}{10.9}[/tex]
[tex]x=Sin^{-1}(\frac{8.9}{10.9})[/tex]
Hence,option D is true.
