Answer:
x=80
Step-by-step explanation:
The sum of interior angles in a quadrilateral is 360°
the square represents a right angle= 90 degrees
124+66+90=280
360-280=80
x=80
Answer:
B?
Step-by-step explanation:
Im pretty sure it would be B because if you subtract 4-2.4 it equals 1.6, same for 9-5.4, the only difference is that it would be 3.6. Sorry if I'm wrong, I tried. :)
(f – g)(x) = 3x + 2 - (2x - 2)
(f – g)(x) = 3x + 2 - 2x + 2
(f – g)(x) = x + 4
You can notice that 14 is 7 time 2, so the answer is 15*2=30. Also, you can use cross multiplication to find your answer.
