Answer:
let y be 126°[vertically opposite angle]
x°+y°=180°[co-interior angle]
x+126°=180°
x=180°-126°
so,x=54°
answer
Via synthetic division, we have
-3 | 1 8 19 12
... | -3 -15 -12
= = = = = = = = = = = =
... | 1 5 4 0
which is to say,
is the area of the base.
Answer:
the third expression
Step-by-step explanation:
x=10.8
(x2 / 18) + 33.52
10.8 x 10.8=116.64
116.64 divide by 18=6.48
6.48 + 33.52=40
