What is the measure of x

mixer [17]

Answer:

x=76 degrees

Step-by-step explanation:

< dij + < jih = 180 straight line

< dij + 107 = 180

subtract 107 from each side

< dij = 73

<jdi + < dij + <idj = 180 triangle

31 + 73 + < idj = 180

combine like terms

104+ < idj = 180

subtract 104 from each side

< idj = 76

<idj = < ajf vertical angles

76 < ajf

<ajf = x

x=76 degrees

PLEASE HELPPPPPP!!!!!!!!

Eduardwww [97]

Answer:

$\sf y=\dfrac{1}{3}x$

Step-by-step explanation:

First find the slope:

$\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{4-5}{12-15}=\dfrac{1}{3}$

Use the point-slope form of linear equation: $\sf y-y_1=m(x-x_1)$
(where m is the slope and (x₁, y₁) is a point on the line)

with the found slope and one of the points:

$\begin{aligned}\sf y-y_1 &=\sf m(x-x_1)\\\\\implies \sf y-4 &=\sf \dfrac{1}{3}(x-12)\\\\\sf y-4 &=\sf \dfrac{1}{3}x-4\\\\\sf y &= \sf \dfrac{1}{3}x\end{aligned}$
