Answer:
x = 15°
Step-by-step explanation:
<em><u>The segment is a diameter, So let us assume the part in which there lies the triangle as a semicircle.</u></em>
=> <em>A triangle inscribed in a semi-circle will always have one of its angle equal to 90</em>
=> <em>So the angle (not 75 and x) is 90 degrees.</em>
<em>=> To find the value of x, we'll subtract rest of the angles from 180 degrees (because the interior angles of a triangle add up to 180°)</em>
<em>So,</em>
=> x = 180-90-75
=> x = 15°

Answer:
the common ratio is 0.98.
Step-by-step explanation:
A fish population in a lake decreases by 2% each year. We are asked to find the common ratio.
The decrease of population of fish 2% annually means the population becomes next year 100% - 2% = 98%
Therefore, the common ratio would be 98%. Upon converting 98 percent to a decimal we will get,
98% = 
Therefore, the common ratio or decay factor is 0.98.
Answer:
224(w)
Step-by-step explanation:
If a household is a four people, that means that each day each of those people drinks 8 servings of water which is 8*4 = 32 servings per day.
Then, there are 7 days in a week so 32*7 = 224 servings in a week
To work this out, you do 46% of 200, as there are 200 customers asked, and the question asks for the number of customers that prefer horror movies, which is 46%.
You can work that out by doing (200 × 46) ÷ 100 = 92.
92 customers prefer horror movies.
