Answer 1

Answer:

SinA = √5/3

CosB = √5/3

Step-by-step explanation:

First let us find the value of a. This is illustrated below:

a^2 = 6^2 — 4^2

a^2 = 36 — 16

a^2 = 20

Take the square root of both side

a = √20 = √(4 x 5) = √4 x √5

a = 2√5

From the diagram,

For sinA

Opp = 2√5

Hypo = 6

Adj = 4

SinA = opp /Hypo

SinA = 2√5/6

SinA = √5/3

For CosB

Opp = 4

Hypo = 6

Adj = 2√5

CosB = Adj /Hypo

CosB = 2√5/6

CosB = √5/3

Answers

Inarithmetic and number theory, the least common multiple, lowestcommon multiple, or smallest common multiple of two integers a and b, usuallydenoted by LCM(a, b), is the smallest positive integer that isdivisible by both a and b. so the LCM of 3a^2b^4c^5 and 7a4bc^2

is a^2bc^2

so the exponent of b is 1

Answer: answer is B(4)
