An architect is sketching a doorway the top of which is part of a circle of radius 50 in the center angle is 100 how many inches
1 answer:
Answer:
The arc length is 87.5 inches.
Step-by-step explanation:
Given that,
Arc length = S = ?
Angle = theta = 100°
Radius = r = 50 inches
The relation between the arc length (S), angle (theta) and radius (r) is calculated using
However, the angle should be in radian.
To convert degrees into radian, we use:
=>
=> 1.75 radian
By putting values in the above relation, we get
Therefore, the arc length is 87.5 inches.

Hello.
First, let the number be r.
5 times r is written like this:
Now, add 45:
Now, the sum of 5r+45 is equal to the sum of 85 and 140:
In order to solve this equation, we need to add 85 and 140:
Now, subtract 45 from both sides:
The last step is to divide both sides by 5:
Therefore, the answer is
I hope it helps.
Have a nice day.
Before you can add or subtract fractions with different denominators.you first have to find common denominators. subtract the numerators and reduce fraction.
Adding fractions make sure numbers are same add the numerators and put it over the denominator,simplify the fraction if needed
