Geometry

any guidance on this problem ?

Step-by-step explanation:

let measure of ∠J=x

measure of ∠K=x+9

measure of ∠ L=x-21

∠J+∠K+∠L=180°

x+(x+9)+(x-21)=180°

3x-12=180

3x=180+12=192

x=64

∠J=64°

∠K=x+9=64+9=73°

∠L=x-21=64-21=43°

J = 48

K = 57

L =>75

Step-by-step explanation:

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
