In isosceles triangle RST below, what is the value of y?

Triangle R S T. Angle T is 38 degrees and angles R and S are y.

y =71

Step-by-step explanation:

The sum of the angles of a triangle add to 180

y+y+38 = 180

Combine like terms

2y +38 =180

Subtract 38 from each side

2y+38-38 =180-38

2y = 142

Divide each side by 2

2y/2 =142/2

y = 71

71°

Step-by-step explanation:

total angle in a triangle is 180

y + y + 38 = 180

2y = 142

y = 71°

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
