Answer:

$8x+13y = 130$

Step-by-step explanation:

sum of interior angles in a triangle is 180 degree

interior angles are (5x+3y)∘,(3x+20)∘, and (10y+30)

add all the angles and make it equal to 180

$5x+3y+3x+20+10y+30= 180$

combine like terms

$5x+3y+3x+20+10y+30= 180$

$8x+13y+x+50= 180$

subtract 50 from both sides

$8x+13y = 130$
