Hey there!

X = 90

In a quadrilateral there is 360 degrees. You add up all the given points and subtract then from 360 and you get 90.

So the answer is D.

Hope this helps !

Answer:

The value of x is D) 90°

Explanation:

The sum of interior angles in a quadrilateral is 360°

As the total interior angles in a quadrilateral is 360 to work this out you would first need to work out the total of the angles given You can do this by adding 101 and 75 and 94, this gives you 270. This is because it tells us how much of that 360 degree total has been used.

The next step is to work out the angle of x. You can do this by subtracting the total angles gives of 270 from the total of 360, this gives you 90 degrees. This is because by subtracting it we are isolating the value of x.

1) Add the values of 94, 101, 75.


101+94+75=270

2) Minus 270 from 360.


360-270=90degrees
