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

y = x + 95

y = 42 + 95

y=137 mm hg

its adding 5.5 each time
