Triangle abc is isosceles. if a and b are equal and 67.5°, what is the degree measure o

measure pf the third angle = 180 - 2(67.5)

= 180 - 135 = 45 degrees (answer)

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
