Answer:
C. ECA = BDA
Step-by-step explanation:
An angle is said to be produced whenever two or more lines meet at a point. An interior angle is an angle form within two lines meeting at a point. Then, alternate interior angles are internal angles that are equal due to alternate theorem. These angles should have equal measures.
From the given question, the alternate interior angles by the theorem is;
ECA = BDA
By the alternate interior angle theorem, the alternate interior angles are ECA and BDA. This implies that the measure of <ECA should be equal to the measure of <BDA.

Answer:
ur mom
Step-by-step explanation:
Well so you have to go with pemdas. p parenthesis, e exponets,m multipication, d division, a add, s subtract. let start with the parenthesis which is 8 plus negative four to the secondpower minus 6. so negative 4 to the second power is equal to positive sixteen because negative time negative is equal to positive. so 8 plus sixteen is 24-6 is 18. negative 12 divided by 3 is negative 4.so negative 4 time 18 is negative 72 plus 2 is negative 70.the answer is negative 70
