Trapezoid yesr is an isosceles trapezoid. if m∠yes= 77 °, what is m∠esr?
a) 77°
b) 113°
c) 103°
d) 13°

C) 103°

Step-by-step explanation:

Because this is an isosceles trapezoid, it will have 2 pairs of equal angles. If angle YES is equal to 77°, that means that the angle that is on the same side as it will also equal 77°. Angles YRS and ERS are also equal. Assume that angle equals x. Knowing this, you can use the equation:

77+77+2x = 360

154+2x = 360

2x =360-154=206

x=206/2

x=103°

because its not ur topic and its not for is for homework not that.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
