Question

angles of triangles are x+30°and 2y+40°and y+50°.write linear equation

Answer 1

we know sum of angle =180°
use this concept ,
x+30°+2y+40°+y+50°=180°

x+3y=180°-120°=60°

x+3y=60°

Answer 2

Answer:t

Step-by-step explanation:

we know that the sum of a triangle=180 degree

so x+30+2y+40 +y+50=180 degree

x+3y+120=180
