Question

Find the value of x

Answer 1

#11 is 67?

Answer 2

Yes 11 is 67

Answer 3

And the second one is 44

Answer 4

11. 2x+46=180
minus 46
2x=134
divide by 2
x=67
13. 2*68+x=180
multiply
136+x=180
subtract 136
x=44

Answer 5

@funfun you can't just give an answer you have to show how you got there

Answer 6

the out side angle is equal to the sum of the two given angles

Answer 7

Well, you know that a triangle equals 180 degrees, so you have to find out what number fits into all the equations

Answer 8

forget my last comment the bottom angles are equal and if you add the outside angle with the not given inside angle you get 180
5x+12+3x8=180
combine terms
8x+20=180
subtract 20
8x=160
divide by 8
x=20
substitute to see if it works
5x+12+3x+8
5*20+12+3*20+8
multiply
100+12+60+8
add
180
x=20
