Given: and are right angles; ; prove: step 1: we know that because all right angles are congruent. step 2: we know that because corresponding angles of parallel lines are congruent. step 3: we know that because it is given. step 4: because of the asa congruence theorem. aas congruence theorem. third angle theorem. reflexive property.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

$12. that is my answer.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
