Please help me, i will make brainliest if correct

x = 7

Step-by-step explanation:

the front triangle is isosceles because it has two sides that are equal which means the angles that created those sides are also equal

so the bottom right angle is also 70 degrees

if two angles are 70 degrees, that adds to 140 degrees

since a triangle has 180 degrees then one portion of the right angle must be 40 degrees and the adjacent angle (∡2) must be 50 degrees

∡2 is 8x - 6 so create this equation:  50 = 8x - 6

8x = 56

x = 7

hope this !
