Isaac determined the measure of each of the four angles in a quadrilateral. the measures of the angles are listed below.

• 62°
• 81°
• 82°
• 132°

isaac claimed that the measures of the angles in the quadrilateral were incorrect. which of the following statements best explains why isaac’s claim is accurate?

the sum of the measures of the angles in a quadrilateral must add up to 180°.

the sum of the measures of the angles in a quadrilateral must add up to 360°.

the sum of the measures of the angles in a quadrilateral must add up to 540°.

the sum of the measures of the angles in a quadrilateral must add up to 720°.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
