In isosceles triangle RST below what is the value of y

y=71

Step-by-step explanation:

The sum of the angles in a triangle is 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

4

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
