2 answers:

You can either ask "How much is left when you take 3 away from 12?", or you can ask "How far apart are the numbers 12 and 3 on the number line?"

Another way you could think about it is "what number do I have to add to 3 to get to 12?"

First, you could count from 3 up to 12 and record the number between them. Second, you could use mental math and try to figure out mentally. The answer is 12-3= 9

An angle measure 34 less than a complementary angle measure of each angle

FinnZ [79.3K]

Answer:

The unknown angle measures 56

Step-by-step explanation:

Complementary Angles:

Two angles are complementary when they add up to 90 degree.

An angle measure 34 less than a complementary angle. Which means angle one is 34 and angles two is 90 minus 34.

angle one + angle two = 90

34 + angle two = 90

angle two = 90 - 34

angle two = 56

Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area.

Alekssandra [29.7K]

Answer:

Area of window = 3 ft²

Area to be painted = 45 ft²

Explanation:

To get the area to be painted, we will start by getting the area of the whole wall (including the window), then subtract from it the area of the window

1- getting area of whole wall:

From the figure, we can note that the length and width of the wall are given as 6 ft and 8 ft

Area of whole wall = length * width

Area of whole wall = 6 * 8 = 48 ft²

2- getting area of window:

Again, from the figure, we can note that the length and width of the window are 2 ft and 18 in (which is equivalent to 1.5 ft)

Area of window = length * width

Area of window = 2 * 1.5 = 3 ft²

3- getting area to be painted:

Area to be painted = area of whole wall - area of window

Area to be painted = 48 - 3 = 45 ft²

Hope this helps :)
