In right triangle ABC with right angle C, sin A = 4/5 and cos A = 3/5. What is sin B + cos B?

so sin B + cos B =

Step-by-step explanation:

in the given right angled triangle angle A and angle B are complementary to each other

so, Sin A = Cos B

and Cos A = Sin B

=》

i believe that is true.

step-by-step explanation:

hope my answer has you if not i'm sorry.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
