Answer:
6
Explanation:
Since a right angle is 90 degrees, first you know that one is 6x + 6 degrees so first you do 90 minus 6 which will give you 6x + 8x = 84 degrees.
so then you do 6x + 8x so that is 14x so then you do 84/14. that is because you want to find what is the value of one x is. (14 is because the 8 plus 6.)
so yeah you get 6 from 84/14. that means x is 6. there's your answer.
just for some proof, let's do it backwards. So first, 8 times 6 is 48. and 6 times 6 is 36 plus 6 which is 42. then, we should find out 48 plus 42 equals 90. hey that's correct! that means our answer 6 is correct.
