Answer:
4+11=15
Step-by-step explanation:
c=4 11=b
4(c) + 11(d) = 15
Step-by-step explanation:
When you move point A horizontally to the right or left, the measures of angles ADC and ADE change, but the sum of their measures is always 180° since angles ADC and ADE are a linear pair and are supplementary, so the sum of their measures is 180°.
The same is true of point B moving horizontally and the measures of angles BEF and BED.
A. 3/4 • 7/8 = 21/32 < 7/8
B. 1 1/3 • 9/10 = 2 1/5 > 9/10
C. 3/4 • 7/8 = 21/32 < 7/8
D. 7/8 • 9/10 = 17/20 < 9/10
A is the correct answer.
