Answer:

The measure of angle z is 115

Step-by-step explanation:

In order to find the measure of the third angle in a triangle, note that all of them should be equal to 180. So we can add them together and set equal to 180.

30 + 35 + z = 180

65 + z = 180

z = 115

Answer:

I don't think the answer exist

Step-by-step explanation:

for y=6x

when y=0, x=0 and when x=0, y=0

hence, (x,y)=(0,0)

for y=x+6

when y=0, x+6=0, x=-6 and when x=0, y=6

hence (x,y) = (-6,6)

for y=x^2+6

when x=0, y=6 and when y=0,

x^2+6=0

subtracting 6 from both sides

x^2=-6

take the square root of both sides and get

x=+ or -sqrt(-6)= + or - (2.45i)

i.e. x=+2.45i or x=-2.45i these are complex roots anyway, and its out of point.

for y=2x+6

when x=0, y=6 and when y=0,

2x+6=0,

2x=-6,

x=-3

the coordinates give (x,y)=(-3,6)

conclude....

I need help... the question is confusing

\bf \stackrel{line~J}{y+8=-(x-2)}\implies y+8=-x+2
\\\\\\
y=-x-6\implies y=\stackrel{slope}{-1}x-6

now we know the slope of line J is -1.

a line perpendicular to J, will have a negative reciprocal slope, therefore,

\bf \textit{perpendicular, negative-reciprocal slope for slope}\quad -1\implies \cfrac{-1}{\underline{1}}\\\\
negative\implies  +\cfrac{1}{{{ \underline{1}}}}\qquad reciprocal\implies + \cfrac{{{ \underline{1}}}}{1}\implies 1

therefore, line K has a slope of 1, and passes through 3,4,

\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
%  (a,b)
&&(~{{ 3}} &,&{{ 4}}~)
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}\implies 1
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-4=1(x-3)\implies y-4=x-3
\\\\\\
y=x+1
