Answer:
A is the correct equation
Step-by-step explanation:
E and B angles are vertical
Answer:
-4/7 is the smallest. then it's -1/19 and then finally it's 7/4
Make a t diagram between two cars
since line AB and CD make all right angles (given) angles 6+7+8 will equal 90 degrees.
According to the verticle angles rule:
angle 2 is equal to angle 6
angle 3 is equal to angle 7
angle 4 is equal to angle 8.
which proves that angle 2+4+7=90 degrees
