Correct option B)
.
<u>Step-by-step explanation:</u>
We have the following figure attached as shown below.
Now, this triangular prism have 2 similar right angled surfaces and 3 rectangular surfaces , Let's calculate area for all of them:
2 similar right angled surfaces
We know that area of triangle = 
⇒ 
⇒ 
⇒ 
But there 2 such surfaces so , 
3 rectangular surfaces
Area of rectangle = 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Total area =
Adding area of 2 similar right angled surfaces & 3 rectangular surfaces:
=
Correct option B) .
40 is the answer for your question
Answer:
A. 560
Step-by-step explanation:
multiply 600 by 0.93 in order to find out what 93% of 600 is.
600 x 0.93 = 558
since 558 isn't one of the options you find which one is closest to it, then divide by 600 in order to see if it's still 93%
a) 560/ 600 = 0.93333 = 93.3%
there's your answer.
but to compare it with the rest of the answer choices:
b) 540 / 600 = 0.9 = 90%
c) 470 / 600 = 0.78333 = 78.3%
d) 490 / 600 = 0.81667 = 81.6%
none of these are in the range of 93, so they're incorrect
A decagon has 10 sides.
The sum of the interior angles is found using the formula S = (n-2)*180, where n is the number of sides.
The total sum of the interior angles of a decagon would be:
(10-2) *180 = 8 * 180 = 1440 degrees.
Now to find the measure of each interior angle, divide the total sum by the number of sides:
1440 / 10 = 144
Each angle is 144 degrees.
