Answer: 40 million
Step-by-step explanation:
Number of families that had TVs in their home in 1980s = 60 million
Number of families that had TVs in their home in 2015 = 100 million
To calculate the increase in TVs that were there in 2015, we subtract the number of families that had TVs in their home in 1980s which was 60 million from the number of families that had TVs in their home in 2015 which was 100 million. This can be expressed as:
= 100 million - 60 million
= 40 million
Step-by-step explanation:
STEP 1:
Find a length of third side.
Use the Pythagorean theorem:
STEP 2:
Use the trigonometric functions:
STEP 3:
Use theorem: the sum of the measures of acute angles of the right triangle is 90°.
Example:
We have the length of legs: a = 3, b = 4.
Let c = hypotenuse.
Use the Pyhagorean theorem:
Angle between a and c (β):
Use sine. Therefore b = opposite, c = hypotenuse:
<em>look at the picture</em>
<em>subtract 37° from both sides</em>
Divide the top one from the bottom one
90 - 48 = 42 complement
180 - 26 = 154 supplement
