Question

fond cos, tan, sin
if cot =4/5​

Answer 1

Answer:

Step-by-step explanation:

cot=4/5

adjacent/opposite=4/5

adjacent=4

opposite=5

hypotenuses=root of 5 square and 4 square

25+16=41

tan=5/4

sin=5/root41

cos=4/root 41

Answer 2

Answer:

Let angle terha be A.

Step-by-step explanation:

If cotA =4/5, tanA=1/cotA

tanA=5/4(opp/adj)

hyp²=opp²+adj²=5²+4²=25+16=√41.

sinA=5/√41.

cosA=4/√41.
