Question

The angles of a triangle re 2y , 3y , and 4y ,find the value of y in degrees ​

Answer 1

2y + 3y + 4y = 9y
180 divided by 9 = 20
Y = 20 degrees

Answer 2

Answer:

y = 20°

Step-by-step explanation:

$Sum\:of\:angles\:in\:a\:triangle = 180\°\\\\2y\°+3y\°+4y\° =180\°\\\\Simplify\\9y\° = 180\°\\\\Divide \:both\:sides\:of\:the\:equation\:by\:9\\\frac{9y}{9} = \frac{180\°}{9} \\y = 20\°$
