Question

Assalaamu alaikum...,

Answer 1

Answer:

see below

Step-by-step explanation:

alaikum salam.

2. find cos Ф,   sin Ф,  tan Ф

cos Ф = 5 / 13

Ф = 67.38

sin Ф = 12 / 13

Ф = 67.38

tan Ф = 12 / 5

Ф = 67.38

-----------------------

3. find sin β,  cos β,  tan β

sin β = 4 / 5

β = 53.13

cos β = 3 / 5

β = 53.13

tan β = 4 / 3

β = 53.13

Answer 2

Answer: Step-by-step explanation

2.

cos Ф = 5 / 13 ,       Ф = 67.38

sin Ф = 12 / 13 ,      Ф = 67.38

tan Ф = 12 / 5         Ф = 67.38

3.

sin β = 4 / 5    β = 53.13

cos β = 3 / 5    β = 53.13

tan β = 4 / 3     β = 53.13
