Point slope formula is what to believe
First you need to expand them
(x^2 + 9) + (2x + 6)
then you add them together
x^2 + 2x + 15
now you can factorise it
i hope this helped you
Answer:
its very easy dude like come on this is like 4rth grade stuff
Answer:
See below.
Step-by-step explanation:
The 3 angles of all triangles add up to 180 degrees.
An isosceles triangle has 2 of its angles equal.
So if one of the angles is 130 degrees then there cant be another one of 130 degrees as that would make 260 degrees.
So the other 2 angles are equal and their measure is (180 - 130) / 2
= 50 / 2
= 25 degrees.
The 2 equal angles are both 25 degrees.
