Answer:
Solve for x: x + 128 = 180, x = 52°
Solve for y: x + y = 90 or 52 + y = 90, y = 38°
Step-by-step explanation:
In order to solve for the measures of ∠x and ∠y, you first need to remember that angles that are complementary add up to 90° and angles that are supplementary add up to 180°. So, in order to solve for 'x', which is supplementary to a 128° angle, we can set up an equation where the sum of ∠x and 128° = 180°:
x + 128 = 180, subtract 128 from both sides: x + 128 - 128 = 180 - 128, x = 52°
Knowing that ∠x + ∠y = 90° and now that ∠x = 52°, we can set up the second equation:
52 + y = 90, subtract 52 from both sides: 52 + y - 52 = 90 - 52 or y = 38°

The original answer is 5.2186. After you round, your answer should become 5.22
Answer:
8.5 × 10^5
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
0 & 1
Step-by-step explanation:
3(1 + x) < x + 6
Distribute
3x+3 < x+6
Subtract x from each side
3x+3-x < x+6-x
2x+3 <6
Subtract 3 from each side
2x+3-3 <6-3
2x <3
Divide each side by 2
2x/2 <3/2
x <3/2
