Answer 7

Every triangle has a total of 180 degrees

Answer 8

So when finding X, the other angle, Angle B, must together with X and 70, equal 180 degrees

Answer 9

Now a right angle looks like this



This is a 90 degree angle, X has a degree that is smaller then this so we can see that A can't be the answer

Answer 10

@ikatouni are you seeing this?

Answer 11

yes but I don't have time can u just tell me wat it is and then explain it pleez

Answer 12

So

\[70 + X + B = 180\]

Minus 70 from both sides of the equation and you get

\[X + B = 110\]

So we know that X + B has to equal 110

Answer 13

110 + 70 would equal in 180 degrees, this would make it a whole triangle

Answer 14

yes so x equals

Answer 15

So looking at the image provided, it states that AB // CD , this means that AB is parallel to CD. So this means that the angle D(46 degrees) has the same amout of degrees as B would.

This means that B is also 46 degrees

Answer 16

that means X=46degrees

Answer 17

So looking back at our old equation,

\[70 + X + B = 180\]

We now know what B is

\[70 + 46 + X = 180\]

Answer 18

Remember that

\[X + B = 110\]

Answer 19

So 46 + what equals 110?

Answer 20

64

Answer 21

Correct :)
