A circle has a 360 degree angle so what I did is i added 85+80+125 and i got 290. 360-290=70
Answer:
21b
Step-by-step explanation:
The shape in the middle is a quadrilateral, so the bottom right hand corner should add up to the rest of the angles to give 360 degrees.
40 + 80 + 110 = 230°
360 - 230 = 130°
The line on which x is on is a straight line, and a straight line is 180 degrees.
Therefore x has to be 180 - 130 to make sure it adds up to give 180 degrees.
180 - 130 = 50
∴ x = 50°
Answer:
x = 9
Step-by-step explanation:
The parallel lines divide the sides of the triangle in proportion, that is
= 
=
( cross- multiply )
8x = 72 ( divide both sides by 8 )
x = 9
Answer:
1024, -4096, 16384
Step-by-step explanation:
The numbers are multiplied by -4
4 x (-4) = -16
-16 x (-4) = 64
64 x (-4) = -256
