Hmm if I'm not mistaken, is just an "ordinary" annuity, thus

Answer:
7 and 3/4
Step-by-step explanation:
31/4=7-3
the remainder is 3/4
D) 30
A polygon can rotate a total of 360. This one has 12 sides and 12 angles that are all congruent. So to coincide with original image, it must rotate 1/12 of the way around
360/12=30
I’ll be happy to help!
Since a right angle is equal to 90 degrees, we can add the 67+90 which equals 157, so since a triangle is equal to 180, we can subtract 180-157.
180-157= 23
The answer for x is 23!
