Suppose a triangle has sides 3 4 and 5, which of the following must be true

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

m∠a is 90°

m∠b is 40°
