Answer:
Step-by-step explanation:
we know that
The measure of the interior angle in an equilateral triangle is equal to 60 degrees
The measure of the interior angle in a regular octagon is equal to
where
n is the number of sides
In this problem we have
substitute
we have that, based in the diagram
The sum of the interior angle of the equilateral triangle plus the interior angle of a regular octagon plus the value of x must be equal to 360 degrees (complete circle)
so
solve for x
Answer:
He should cross multiply 90 and 60, and then divide by 100. The answer is 54.
Answer: 1
Step-by-step explanation:
12-8=4
12-8=4
4 over 4 is 1
if it perpendicular then it's the opposite reciprocal
hope that help
1. get rid of your parenthesis
2. in order to do so you must look inside of the parenthesis and check if you have any like terms if so combine them
3. next use the distribution property or otherwise known as the rainbow
4. if you have an exponent to the right of your parenthesis then use the exponent rule
5. combine like terms by adding coefficients
6. finally combine the constants
