Step-by-step.
30255.5=a90.75
Step 1: Cross-multiply.
30255.5=a90.75
(3025)*(90.75)=a*(5.5)
274518.75=5.5a
Step 2: Flip the equation.
5.5a=274518.75
Step 3: Divide both sides by 5.5.
5.5a5.5=274518.755.5
a=49912.5
Answer:
Interior: 135 degrees
Exterior: 45 degrees
Step-by-step explanation:
The interior angle of a regular octagon is exactly 135 degrees, which can be found using the (n – 2)180 formula. The exterior is simply 180 - the interior, which is 45. :)
7B = 9B - 180
REARRANGE THE VARIABLE ON ONE SIDE AND NUMBER ON THE OTHER SIDE.
we get,
180 = 9B -7B
180 = 2B
therefore B = 180/2
= 90 CALORIES IS THE ANSWER
