A composite number is a positive integer. which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... (OEIS A002808), whose prime decompositions are summarized in the following table.
Step-by-step explanation:
3, 4, 5
6, 8, 10,
5, 12, 13 and there are several other Pythagorean triplets which can form a right triangle.
Answer: 84
Explanation:
Total for 5 tests = 80 x 5 = 400
Total for 4 tests = 84 + 75 + 81 + 76 = 316
5th score = 400 - 316 = 84

Answer:
Option (C)
Step-by-step explanation:
Since angle 'a' is the inscribed angle of the given triangle
Therefore, angle measure of the intercepted arc will be equal to the double of the inscribed angle.
x = 2a ⇒ a =
By the tangent-chord theorem,
"Angle between a chord and tangent measure the half of the angle measure of intercepted minor arc"
= 40°
Therefore, a = = 40°
Option (C) will be the answer.
