Answer:
162 degrees
Step-by-step explanation:
Angles P and F are supplementary, so ...
3x^2 +12x = 180
x^2 +4x = 60
x^2 +4x -60 = 0
(x +10)(x -6) = 0
The useful value of x that makes this true is x=6.
The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:
∠S = 180° -18° = 162°
let the number be x.
a number decreased means
x-
and the sum of the number and 4 is
x+4
to put the expression together, we get. put them in parentheses
x - ( x+4 )
= x - x -4
= - 4
Answer:
The answer is (5,-6)
Step-by-step explanation:
it's the only point that's both on the line and and further away from point A
(180-144)° + 3x + 90° = 180°
36 + 3x + 90° = 180°
x = 18°
