There's 180 degrees in a triangle so and the two angles and then subtract by 180
5 (x + 30) is your answer
you will distribute the 5 to both x and 30, as there are 5 thirty's and 5 x's
hope this helps
May Joan of Arc give you good tidings lol*
Answer:
x = -5/2 + root(33)/2 or x = -5/2 - root(33)/2
Step-by-step explanation:
ok so your computer is
saying:
x^2 + 5x = 2
and takes the 5 divides it by 2 and squares the result
x^2 + 5x + 25/4 = 2 + 25 /4 but then replaces a trinomial with a binomial
(x + 5/2)^2 = 2 + 25/4 = 33/4
solving
x = -5/2 + root(33/4) or x = -5/2 - root(33/4)
or
x = -5/2 + root(33)/2 or x = -5/2 - root(33)/2
