Answer:
Step-by-step explanation:

= 160
answer = not define
Step-by-step explanation:
slope = (y2- y1) / (x2- x1)
= 9-3 / 7-7
= 6/0
= not define
I think points are wrong
C. -2 because if you substitue the 2 in for x and then solve you get your answer
Answer:
the parameter equation of given line is
x= 1+t
y=0+ 2t
z= 9+t
( note: in plane no signs given so we assume + so x+2y+z)
Step-by-step explanation:
A vector perpendicular to the plane a

So a vector perpendicular to the plane x

The parametric equation of a line through
and parallel to the vector ⟨
a
,
b
,
c
⟩ is

so the parametric equation of our line is

The vector form of the line is
Answer:
solution given:
3(x+2)+35°+52°=180°[sum of interior angle of a traingle is 180°]
3(x+2)=180-87
x+2=93/3
x+2=31
x=31-2=29°
value of x=29°
again
<C=3(29°+2)=93°
the measure of angle C=93°
