58 ÷ 6 = 9/2/3
i am a mathematics teacher. if anything to ask please pm me
me at 1:36pm: oh no, i hope he got his answer
Answer:
14x+19x+8-8
=33x
because 8-8 is 0 always so the answer is 33X
6w-y=2z
6w=2z+y
w=(2z+y):6
w=(z:3)+(y:6)
Answer:
see explanation
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
The polygon here has 8 sides, that is n = 8, thus
sum = 180° × 6 = 1080°
Sum the given angles and equate to 1080, that is
14x + 133 + 167 + 138 + 18x + 115 + 151 + 120 = 1080
32x + 824 = 1080 ( subtract 824 from both sides )
32x = 256 ( divide both sides by 32 )
x = 8
Thus the 2 unknown angles are
14x = 14 × 8 = 112°
18x = 18 × 8 = 144°
