Answer:
390cm³
Step-by-step explanation:
IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.
All you need to do is solve for the volume of each prism and add them up together.
The formula to use to get the volume of a rectangular prism is:
Where:
V = Volume
w = width
l = length
h = height
Let's get the first one and double it because you have rectangular prisms with the same dimensions:
Next we get the rectangular prism in the middle:
Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.
12cm - (5cm + 2cm)
12 cm - 7cm = 5cm
Then we plug it into the formula
Now that we have the volumes of all figures, just add them up together:
150cm³ + 240cm³ = 390cm³
If we knew that two angles were complementary and were given the measure of one of those angles, then we can find the measure of the other angle by subtracting the given measure of one angle from 90
<em><u>Solution:</u></em>
Given that,
If you knew that two angles were complementary and were given the measure of one of those angles, would you be able to find the measure of the other angle
Yes we can find the measure of another angle
<em><u>Complementary angles:</u></em>
Complementary angles are two angles whose sum is 90 degrees
Therefore, if measure of one angle is given, then we can find the measure of another angle
Measure of another angle = 90 - measure of one angle
<em><u>Example:</u></em>
If x and y are complementary angles
Given that measure of angle x is 45 degrees
Then we can say,
According to complementary angles definition
x + y = 90
45 + y = 90
y = 90 - 45
y = 45
Thus measure of other angle y is found to be 45 degrees
