Which could be the measures of the angles of a quadrilateral? A. 80° , 90° , 80° , 110°
B. 65° , 73° , 151° , 73°
C. 88° , 99° , 110° , 77°
D. 40° , 60° , 80° , 90°

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
