What is x in the equation 2x + 6 = 12

vfiekz [6]

Answer:

x=3

Step-by-step explanation:

First you subtract 6 from both sides to get the x on one side and the numbers on the other. So, the equation would become 2x=6, and then you divide each side by 2 to get x=3.

Given the measure of three angles in a quadrilateral, find the measure of the fourth angle.1. 40 degree , 120 degree , 100 degre

Veronika [31]

Recall that the interior angles of a quadrilateral add up to 360 degrees.

1) Let x be the measure of the missing angle, then we can set the following equation:

$40^{\circ}+120^{\circ}+100^{\circ}+x=360^{\circ}.$

Solving for x we get:

$\begin{gathered} 260^{\circ}+x=360^{\circ}, \\ x=100^{\circ}\text{.} \end{gathered}$

2) Let y be the measure of the missing angle, then we can set the following equation:

$73^{\circ}+107^{\circ}+122^{\circ}+y=360^{\circ}\text{.}$

Solving for y we get:

$\begin{gathered} 302^{\circ}+y=360^{\circ}, \\ y=58^{\circ}\text{.} \end{gathered}$

Answer:

1) 100 degrees.

2) 58 degrees.

What is the value of y in the figure if x = 30°?<br> y =

QveST [7]

Answer:

y is 150

Step-by-step explanation:

a straight angle always measures 180 degrees. if x is 30, the simply minus 30 from 180. that should give u 150 which is your answer.

hope this helped!
