Question

what is the value of x?

Answer 1

Answer:

x = 7

Step-by-step explanation:

Since all angles have to sum up to 180° and since we know that I angle in the right angle triangle is 90° already hence we can find x algebraically:

$8x + (4x + 6) + 90 = 180\\8x + 4x + 96 = 180\\12x = 84\\\therefore x= 7$
