2geometry questions.. will mark brainliest

1=given the result from c above, if the measure of angle efb is 43.6°, what is the measure of angle fbc? how do you know?

2=if triangle dcb is congruent to triangle abc, what kind of shape is abcd? how do you know?

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
