Step-by-step explanation:
As the two equations have an intersection at (-5,1), which means they share the same point, then (-5 , 1 ) is the solution for the system.
Answer:
Step-by-step explanation:
sin(x°) = 4/5
x° = arcsin(4/5) ≅ 53.1°
Given:
In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.
To find:
The value of sine of ∠J.
Solution:
In a right angle triangle,

In triangle JKL,




Therefore, the value of sine of ∠J is about 0.44.
