Answer:
25. a = 60
26. a = 17
Step-by-step explanation:
In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure
so we have
25.
and for 26 we have
This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying . This is the second line. Then, you could take the square of the 
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
Answer:
m= 2/17
Step-by-step explanation:
do the formula x1 and y1 and x2 and y2
x1, y1 x2, y2
(-11,15) (23,19)
when subtracting you ALWAYS START WITH YOUR Ys
19-15= 4
now subtract your Xs
23- (-11)= 34
now your answer is 4/34
but that's not the last step you can simplify it and make it smaller,
they both go into 2 so know divide both of then numbers by 2
and you should get 2/17
your final answer should be 2/17
Answer:
d=4.14
Step-by-step explanation:
use the equation d=2r
d=C/π=13/π≈4.13803
4.13803≈4.14
