Find the value of x in each figure.
12.
14004+ 1210

x = 28

Step-by-step explanation:

(x + 12) and 140 form a straight angle and are supplementary, thus

x + 12 + 140 = 180, that is

x + 152 = 180 ( subtract 152 from both sides )

x = 28

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
