congruent
Step-by-step explanation:
If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. When two adjacent angles form a linear pair, their non-shared sides form a straight line (m).
i'm not sure tho
Answer:
tanA =
Step-by-step explanation:
Before obtaining tanA we require to find EF
Using Pythagoras' identity in the right triangle.
EF² = DF² - DE² = ( )² - 7² = 60 - 49 = 11 ( take square root of both sides )
EF =
Then
tanA = = =
I believe you just add all the numbers then divide by how many were there. You would divide by 16.
