As you see this is a right angle, so the sum of the two angles = 90°
So,
(x + 42) + 3x = 90°
Remove the parentheses:
x + 42 + 3x = 90
Combine like terms:
4x + 42 = 90
Subtract 42 on both sides:
4x = 48
Divide 4 on both sides:
x = 12

Now, Percent of increase.
<u>Increase carbon-dioxide levels</u>:— 50.
<u>Percent increase</u>:— 13.62%
Answer:
w = -16.
Step-by-step explanation:
14 = -7/8w
To isolate w on the right side we multiply both sides by -8/7:
14 * -8/7 = -7/8 * -8/7 w
-16 = w.
