Answer:
x = 128
Step-by-step explanation:
x and 128 are vertical angles
Vertical angles are equal
x = 128
Hi there!
We can solve for x knowing that the sum of interior angles in a triangle is 180°.
The square at the bottom indicates a right angle, or 90°. Therefore:
180 = 90 + x + (x + 10)
Combine like terms:
180 = 100 + 2x
Subtract 100 from both sides:
180 - 100 = 2x
80 = 2x
Divide both sides by 2:
x = 40.

-2 is the answer. You have to divide the second term by the first term or the third term by the second term.
-14/7 = -2
<span>3x - 4y = 8
</span>4y = 3x - 8
y = 3/4 x - 2 ; slope = 3/4
parallel lines have same slope
so answer is C. 3/4
