sinФ = opposite/hypentenous
sin35 = x/20
0.574 = x/20
cross multiply
x = 20(0.574)
x = 11.48
Round to the nearest tenth.
x = 11.5
Answer:-20
Step-by-step explanation:
The answer is negative 20 because if you do -20 times 5 you get -100. So you now you are right when you did a check step that worked

Answer:
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
Step-by-step explanation:
As the test is targeted to 18-to-29-year-old adults using social media, we want to know the probability that a randomly selected adult uses social media and belong to the study group.
To achieve this, we have this data:
- 36% of all adults do not use social media
- 75% of all adults are >30 years old.
- The percentage of population that is <em>either</em> 18-29 years old <em>or</em> uses social media is 66.7%
Using the last data we have that

The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
