The best way to solve for x is to first solve for y and then subtract values. The top of "line" of the 3 angles togethers add up to 180 degrees. So from this, you can deduct this equation into
. To solve for y, subtract
and
from the left hand side and rights hand side of the equation. now you know the value is
. So the value of y is 69 degrees.
Now you know two angles of a triangle and the sum of the angles in a triangle is 180 degrees. So the equation is
. To solve for x, subtract
from both sides.
. So you know that
degrees.
13 and 1/2. This is because 4.5 times 3 is equal to 13.5
Answer:
C
Step-by-step explanation:
You read piece wise as
2 turns on at x = -5, then turns off at x = - 1 and so on
Answer:
1) -15+8i
2) x^2+2x-5
Step-by-step explanation:
1) apply perfect square formula
(4i)^2+2*4i1+1^2
then simplify
2)remove parentheses
x+1+(x-2)(x+3)
expand (x-2)(x+3)
x+1+x^2+x-6
simplify x+1+x^2-6 = x^2+2x-5
Answer:
i think its $116
Step-by-step explanation:
if you have four groups of twenty-nine dollars that would be
4x$29
which is $116
