EXTRA POINTS :) what is the value of x??

vlada-n [284]

Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180° then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180 subtract 10 from both sides

-10 -10

10x = 170 divide each side by 10

/10 /10

x = 17

4x - 7y = 3 <br> x - 7y = 15

charle [14.2K]

$\left \{ {{4x-7y=3} \atop {x-7y=15}} \right. \\\\
 \left \{ {{4x-7y=3} \atop {x=15+7y}} \right. \\\\ substitution\ method\\\\
4*(15+7y)-7y=3\\\\
60+28y-7y=3\\\\
60+21y=3\ \ \ \ | subtract\ \\\\
21y=-57\\\\
y=-\frac{57}{21}=-\frac{19}{7}\\\\
x=15+7*(-\frac{19}{7})=15-19=-4\\\\\ Solution :\ \left \{ {{y=-\frac{19}{7}} \atop {x=-4}} \right.$

Triangle and polygon practice, help please!! Even just with one of them!

deff fn [24]

Step-by-step explanation:

For question no. 3

Since we are aware that measure of the sum of all the three interior angles of a triangle is 180°.

$135 \degree + 25\degree +( 2x + 2)\degree = 180 \degree \\ \\ \therefore \: 2x\degree = 180 \degree - 152 \degree \\ \\ \therefore \: 2x\degree = 28 \degree \\ \\ \therefore \: x\degree = \frac{28 \degree}{2} \\ \\ \therefore \: x = 14$
