Answer:
Option 2nd is correct
67°
Step-by-step explanation:
Given that:
In right △ABC with right angle B.
, m∠A=(3x−8)° and m∠C=(x−2)°.
We know that the sum of all the measures of a triangle is 180 degree
In triangle ABC
⇒
Substitute the values we have;
Subtract 90 degree from both sides we have;
Combine like terms;
Add 10 to both sides we have;
Divide both sides by 4 we have;
then;
m∠A=(3(25)−8)° = (75-8)° = 67°
Therefore, the measure of angle A is, 67°

<h2>Hello!</h2>
The answer is: 23.77 hours
<h2>Why?</h2>Where:
Total(t) is equal to the amount for a determined time (in hours)
<em>Start</em> is the original amount
<em>t </em>is the time in hours.
For example, it's known from the statement that the bacteria double their population every 15 hours, so it can be written like this:
To calculate how long it takes for the bacteria cells to increase to 300, we should do the following calculation:
So, to know if we are right, let's replace 23.77 h in the equation:
Total(t)=100*2^\frac{23.77}{15}=299.94
and 299.94≅300
Have a nice day!
Answer:
I took the test!!
Step-by-step explanation:
Pit this in your calculator exactly like this 4,000(1.05)^5 and you get the answer 5,105.12625. So round your answer to the nearest dollar, which is 5,105.
