X would equal 70°.
For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.
I hope this helps!
Answer:
it's your first answer of
y= (-7/8)x + 1/2
V= 3 x 4^2 x 12
v= 576cm^3
UW is a diameter.
(a). Angle UVX = 23 degrees
(b). Angle UWV = 23 degrees
