Answer:

Answer: x=65

Step-by-step explanation:

Since they're vertical angles both sides are equal to 145 degrees

So, 145-15= 130 to get rid of the constant

Then, 130/2=65

To check you work add up all of your solutions to get 145

2*65=130 & 130+15=145

Therefore, x=65

Answer:

x = 56°

Step-by-step explanation:

DAF is a straight line so it has a measurement of 180°

180° - 64° - 60° = x

x = 56°

Find the point that is two-thirds of the way from (3,4) to (9,-2)

hoa [83]

Keeping in mind that, the segment is split in three thirds, and the point is 2/3 of the way, so is closer to (9, -2), with a 2:1 ratio, check the picture below.

$\bf \left. \qquad \right.\textit{internal division of a line segment}
\\\\\\
A(3,4)\qquad B(9,-2)\qquad
\qquad 2:1
\\\\\\
\cfrac{AC}{CB} = \cfrac{2}{1}\implies \cfrac{A}{B} = \cfrac{2}{1}\implies 1A=2B\implies 1(3,4)=2(9,-2)\\\\
-------------------------------\\\\
{ C=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)}\\\\
-------------------------------$

$\bf C=\left(\cfrac{(1\cdot 3)+(2\cdot 9)}{2+1}\quad ,\quad \cfrac{(1\cdot 4)+(2\cdot -2)}{2+1}\right)
\\\\\\
C=\left( \cfrac{3+18}{3}~~,~~\cfrac{4-4}{3} \right)\implies C=\left( 7~~,~~0 \right)$
