The three inside angles of a triangle need to equal 180 degrees.

This means X = 180 - 43 - 59 = 78 degrees.

X and Z make a straight line that also needs to equal 180 degrees,

so Z = 180 - 78 = 102 degrees.

Y = 180 - 102 - 13 = 65 degrees.

X+3y=28 when x =28 find the value for y plz help

Lisa [10]

Answer:

y = 0

Step-by-step explanation:

Plug in 28 for x. Solve for the equation:

x + 3y = 28

(28) + 3y = 28

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:

28 (-28) + 3y = 28 (-28)

3y = 0

Isolate the variable, y. Divide 3 from both sides:

(3y)/3 = (0)/3

y = 0

y = 0 is your answer.
