Answer:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
Answer:
x = 8
Step-by-step explanation:
Add the four angles given to get 264°
Subtract 264° from the total measure of angles in the pentagram (360°) which gives you 96° for the missing angle measure. From there, it's just basic algebra.
x = 96 ÷ 12
x = 8
Answer:
2.06×10^14
Step-by-step explanation:
nth term of G.p = ar^n-1
the first term, a = 3 common ratio, r = 2nd term/ 1st term, 3rd term/ 2nd term, etc.
r = 9/3 = 3
30th term = 3(3)^30-1 = 2.06×10^14
