Between the time iko woke up and lunchtime, the temperature rose by 11. Then by the time he went to bed, the temperature dropped by 14.

Write an addition expression for the temperature relative to when iko woke up.

11 - 14

Step-by-step explanation:

Let's call the temperature when iko woke up: T

Between the time iko woke up and lunchtime, the temperature rose by 11. This means that the temperature at that time was the previous one plus 11: T + 11

Then by the time he went to bed, the temperature dropped by 14. This means that the temperature at that time was the previous one less 14: T + 11 - 14

To compare this temperature to the initial temperature T, we have to subtract it: T + 11 - 14 - T = 11 - 14 = -3. This means that the temperature at the end of the day was 3 degrees less than at the beginning

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
